ABSTRACT Using Remote Sensing and GIS techniques to build the map of forest resources, determine the biomass and carbon stock of forest, are a new direction in the application of geospatial technology and cost effective method to inventory in forestry The overall objectives of this study are to map out forest cover using SPOT-5 image and establish a map of forest carbon in Cuc Phuong commune, Ninh Binh province The overall objectives of this study are to map out forest cover using SPOT-5 image and establish a map of forest carbon in Cuc Phuong commune, Ninh Binh province ECognition Developer, ArcGIS and MapInfo softwares were used for classification and mapping Based on the results of classification indices from ground survey, segmented imagery of SPOT-5 and NDVI index were classified into land cover classes: (1) rich forest, (2) medium forest, (3) poor forest, (4) restored forest, (5) bamboo forest, (6) plantation forest, (7) water body, (8) Others With total area of study site is 13,109.84 Results showed that the total forest carbon in Cuc Phuong National Park is 1,480,000 tons This rich forest is the largest 9447.62ha, (represent 70.07% total), with the volume of forest is 298.1 (m3/ha) and 257,493.81 ton carbon (represent 85.52% in total) Restored forest is the lowest, with 203.74 (m3/ha), 8,126.96 ton carbon (represent 0.55 % in total).The carbon stock and CO2 absorbed for rich forest in forest at Cuc Phuong commune with the highest value around 133.1 ton/ha and 488.04 ton/ha, respectively viii I INTRODUCTION Forests cover approximately 30% of the world’s total land mass (FAO, 2010) and are an integral part of life on earth, providing services at local, national and global levels But the impacts of climate change are far-reaching, and will also affect forests, and the livelihoods of people who depend on them Scientists have predicted that by 2100, global temperatures will rise from 1.8 to ° C again and sea level will likely rise at about 0.75 - 1.5 m due to the greenhouse effect Greenhouse effects are caused by several factors which include dust, steam, industrial emissions (which mainly some substances are listed in the order: CO2, CFC, CH4 ) of the plant and equipment, vehicles that use fossil fuels, carbon stem, volcanic activity, the nuclear explosion caused environmental pollution Deforestation and forest degradation is also an important factor - this is a source of greenhouse gas emissions significantly contribute to climate change (according to the report submitted at the meeting to discuss US climate group held in Bonn, Germany on 30/03/2009, the "deforestation is responsible for nearly one fifth operation overall greenhouse gas emissions"), this situation dose not only occurs in developing countries in the tropics, but in recent years the "forest fire incident" has occurred frequently and more severe even in developed countries like USA and Russia - which destroyed thousands of hectares of forest / crop Studying the role of forests in protecting the environment, as well as its ability to provide direct use, such as timber, wood, non-timber forest products etc., have implemented in many countries around the world including in Vietnam The value of carbon absorption capacity of forests plays a very important role in the elimination of greenhouse gases, thus contributes to reducing global climate change Value for carbon sequestration by forests could be commercialized under various mechanisms such as payment for environmental services (PES) and Reducing Emissions from Deforestation and Forest Degradation in tropical countries (REDD & REDD + ) The Clean Development Mechanism (CDM - clean development mechanism) provided for in Article 12 of the Kyoto Protocol (KP) of the Convention of the United Nations Framework on Climate Change (UNFCCC) for developing countries states that the CO2 that the plantations to absorbed CO2 is regarded as a measure to reduce greenhouse gas emissions, however, the value of qualitative research and the benefits in terms of new environment is just the first step in the world and is a completely new issue in Vietnam In recent years, the advancement of Geographical Information Systems (GIS) and Remote Sensing (RS) technologies provide valuable information on natural resources management Recent improvements in satellite imagery availability allowed researchers to perform image analysis at much larger scale than in the past Currently, Remote Sensing is widely used to collect information regarding forest above-ground biomass (AGB) and vegetation structure as well as to monitor and map vegetation biomass and productivity on large scales which is done by measuring the spectral reflectance of the vegetation However, optical RS does not directly assess above-ground forest biomass, and radiometry is sensitive to vegetation structure (i.e., crown size and tree density), texture, and shadow, which are correlated with AGB, particularly in the infrared bands (Lu, D et al., 2013) RS data are now considered to be the most reliable method of estimating spatial biomass in tropical regions over large areas RS technology has been applied to biomass assessment in many studies (Kankare et al., 2013) because it can obtain forest information over large areas at a reasonable cost and with acceptable accuracy based on repetitive data collection with minimal effort (Lu, D et al., 2006) Forest have long been regarded as a nation treasure in Cuc Phuong national park In addition, those forests provide resources such as grazing land for animals, wildlife habitat, water resources, timber and non-timber products for local people However, human activities are posing a serious threat to quality and quantity of forest Studies to quantify carbon Figure 4.4.1: The CO2 absorbed map in Cuc Phuong commune Table 4.4.1: The CO2 absorbed in Cuc Phuong National Park at Cuc Phuong Commune Carbon CO2 absorbed ton/ha ton/ha Plantation

indicated the CO2 absorbed in forest at Cuc Phuong commune with the highest value at 488.04 ton/ha 26 for rich forest and the lowest value is 146.26 ton/ha (represent 144.87 ton/ha) for restored

forest constitutes the largest amount of carbon absorb with the high price is 2440.17 USD $/ ha, followed by medium forest and poor forest, with 1982.75 USD $ and 1161.60 USD $ respectively Plantation and Restored forest are by far the lowest figure, with 1008.15 and 731.2 USD $ The key driver of this different is that these forest types are not even age Growth index and density are not equal, leading to the different in capacity of carbon absorb 4.3 Proposing solutions to improve the management of forests in Cuc Phuong commune As the results of findings in the study through previous sections, realized that Cuc Phuong National Park Hanoi has several problems with forest volume and carbon stock such as: lack of land use planning, management board have not completed and management plan have not carried effectively Furthermore, Cuc Phuong National Park has an area of relatively large old forest, the growth and development reached the maximum value and tends to degradation In addition, the land area is relatively large drum, causing high erosion risk while meeting the heavy rains Based on these reasons, subject suggests some solutions to improve the quality of the forest for management of carbon stock and carbon dioxide absorbed in Cuc Phuong Commune: Affairs, exchange of forests forest land and enhancing cooperation in management Individuals or organizations assigned land and forests, the state should clearly define the rights and obligations when using timber In addition, those components are assigned to forest tree management will be responsible before the law for violations Strengthen inspection and strict control handle cases of forest encroachment, conversion of land use purpose that is unlawful The application of information technology into management and monitoring changes in forest resources processes such as organizations and units who own protection forest should 28 participate fully in managing and monitoring changes in forest resource by using database system on the computer at the local and the whole province Encouraging investment in policy support by combining ecotourism development with forest protection programs should be carried out from domestic and foreign sources Moreover, propagating and educating people about the role of forests for mankind and the living environment, especially the young generation should also be prioritized 29 V DISCUSSION The study performed mapping the forest carbon of Cuc Phuong National Park at Cuc Phuong commune with three different maps, including mapping forest volume, mapping forest carbon and mapping the carbon dioxide absorbed in study area As the first map about forest volume of Cuc Phuong National Park at Cuc Phuong commune, with total area of study site is 13,109.84 with eight classes, namely water, plantation, bamboo forest, restored forest, poor forest, medium forest, rich forest and others However, the water, bamboo and others are not responding the forest volume because the study focused on five types of forest with highest volume value is rich forest The lowest volume value is restored forest due to replantation and recovers types of forest The next result of the thesis is mapping the carbon stock in study area The total forest carbon in study area around 1,480,000 tons, in figure 4.3.1 showed the highest value is 133.10 ton/ha This is higher than total carbon, around 130 ton/ha and 1,023,726 ton carbon, in Kim Boi District, Hoa Binh Province compared to the result of Assoc Pro Dr Tran Quang Bao, 2013, identified the carbon stock of forest classes in Kim Boi District, Hoa Binh province The final result of this thesis is mapping the carbon dioxide absorbed in Cuc Phuong National Park The result indicated that the total CO2 absorbed in Cuc Phuong Commune is quite high, with the highest value around 488.04 tons/ha The thesis indicated that the forest in Cuc Phuong commune has the high carbon volume, stock, and carbon dioxide absorbed There are some of reasons can discussion about Cuc Phuong National Park is a natural forest, the rich forest in here to be very available, variable and mainly natural wood forest evergreen broadleaf limestone rich in primary In this case, compared to other researches, Cuc Phuong National Park is rich and need to protect for future about animals and plants, wildlife as well as 30 VI CONCLUSION In conclusion, the results of study demonstrated that applying remote sensing technology and the use high resolution satellite images to forest investigation, especially in the process create map for monitoring the change of the forest type area and forest quality were high accuracy of interpretation, 83.75 % As using the satellite image SPOT the main land cover/land use categories of Cuc Phuong commune include rich, medium, poor, restored, bamboo, plantation forest, water and others With total area of study site is 13,109.84 and total forest carbon is 1,480,000 tons The study presented that the rich forest is largest 9447.62 ha, (represent 72.07% total), with the volume of forest is 298.1 (m3/ha) and 1, 257,493.81 ton carbon (represent 85.52 % in total) Restored forest is the lowest, with 203.74 (m3/ha), 8,126.96 ton carbon (represent 0.55 % in total) The carbon stock and CO2 absorbed for rich forest in forest at Cuc Phuong commune with the highest value around 133.1 ton/ha and 488.04 ton/ha, respectively Besides, the study still has some existing problems, such as: not enough time and cost to collect more field data, my limited knowledge, skills and experiences To overcome shortcomings and achieve better results Further study should be conducted to collect more information about future planning, increase the number of sample plots in forest types and improve user’s skills in applying geospatial technology 31 REFERENCES Adams, R.M., C.C Chang, B.A McCarl, and J.M Callaway 1993 Sequestrating Carbon on Agricultural Land: A Preliminary Analysis of Social Cost and
