| 摘 要： | 森林生态服务价值的研究对构建绿色GDP核算体系、制定生态补偿标准、提高人类环境保护意识等有十分重要的意义。本文首先以卫星影像、地理空间数据、站点记录等资料，结合GIS、RS技术，估算了浙江省森林生态系统2010年的NPP、蒸散量、土壤保持量等；然后，采用能量替代法、机会成本法、影子工程法等估算了浙江省森林2010年的固碳释氧价值、有机物生产价值、水源涵养价值、营养物循环价值、水土保持价值；最后，对各种生态服务价值的逐月变异规律进行分析。结果表明：浙江省森林2010年的5种生态服务价值呈现明显的逐月变异规律；固碳释氧价值、有机物生产价值、营养物质循环价值、水土保持价值的逐月变异规律，均可用开口向下抛物线拟合；水源涵养价值的逐月变异规律，可用开口向上抛物线拟合。

| Abstract: | The research of forest ecosystem service value is very important for the construction of green GDP, the formulation of Ecological Compensation Standards, the improvement of people＆#39;s environmental protection consciousness, and so on. With the development of GIS （Geographic Information System） and RS （Remote Sens-ing）, more and more researchers apply them to the estimation of ESV （Ecosystem Service Value）, so as to realize a dynamic, fast, and space discrepant estimation of ESV. In this paper, based mainly on satellite imagery, geo-spatial data, site record, and combined with GIS and RS technology, we firstly calculated NPP, evapotranspi-ration, soil conservation amount of Zhejiang＆#39;s forest ecosystem in 2010. Then, we calculated the value of carbon sequestration and oxygen release based on NPP and Afforestation Cost Method, the value of organic production based on NPP and Energy Substitution Method, the value of water conservation based on precipitation, evapo-transpiration, and Shadow Project Approach, the value of nutrient recycling based on NPP and Shadow Pricing Method, and the value of soil and water conservation based on soil conservation amount and Opportunity Cost Approach. In the end of this research, the monthly variation of ecosystem service value is analyzed. The analysis results showed that：based on the technology of GIS and RS, we can estimate the value of forest ecosystem ser-vice value dynamically and fast. In 2010, the total quantity of different ESV provided by forest ecosystem of Zhe-jiang Province varied in different months. The biggest one from January to June and December is the value of water conservation;however, the biggest one from July to November is the value of carbon sequestration and ox-ygen release. Different kinds of Ecosystem Service Value changed regularly from month to month;the monthly variation of carbon sequestration, oxygen release, organic production, nutrient recycling, and soil conservation could be fitted with downwards parabola;the monthly variation of water conservation could be fitted with up-wards parabola. The research of this paper has important significance for the establishment of the green GDO ac-counting system, monthly ecological compensation of the returning farmland to forest project, the improvement of people＆#39;s environmental consciousness, etc. |
