%X 森林作为地球陆地上最主要的植被类型之一，不仅创造了适宜生物生存的栖息环境，还孕育了丰富多彩的动植物物种，是人类获取生存资料的主要源泉。基于常德市森林资源的不同种类及特点，建立森林生态系统服务价值评估的指标体系，再运用GIS遥感影视技术、影子工程替代法、市场替代法等方式，计算其吸收二氧化碳、释放氧气、固土和保肥的实物量和价值量，进而核算固碳释氧和土壤保育价值，建立一个部分的森林生态系统服务价值的核算系统。最后得出常德市森林生态系统的固碳价值为77.39亿元/年，释氧价值为5932.38亿元/年，固土价值为32.70亿元/年，土壤营养元素价值量为14522.89亿元/年，保育土壤总价值为14555.59亿元/年。可见，常德市森林生态系统对经济社会发展有着不可或缺的推动作用。<br />
Forest, as one of the most important vegetation types on the earth, not only creates the habit en-vironment suitable for the survival of organisms, but also breeds rich and colorful plant and animal species. It’s the main source for humans to obtain survival information. Based on the different types and characteristics of forest resources in Changde City, the index system of forest ecosystem service value assessment was established, and then GIS remote sensing technology, shadow engineering substitution method, market substitution method and other methods were used to calculate the carbon fixation oxygen release and soil conservation value, and establish a part of the accounting system of forest ecosystem service value. Finally, it is concluded that the carbon sequestration value of the forest ecosystem in Changde City is 7.739 billion yuan/year, the oxygen release value is 593.238 billion yuan/year, the soil fixation value is 3.270 yuan/year, the soil nutrient element value is 1455.289 billion yuan/year, and the total value of the conservation soil is 1455.559 billion yuan/year. It can be seen that the forest ecosystem of Changde City plays an indispensable role in promoting economic and social development.
