| 摘 要： | 通过评价不同管理方式下区域生态系统关键功能的得失，分析了万全镇各种生态系统功能及其空间分布特征，根据不同的发展需求建立情景并对其进行权衡.结果表明: 2009年，万全镇各种生态系统提供的支持功能价值为0.58亿元，以释氧功能（0.37亿元）为主；调节功能价值为12.38亿元，以气候调节（11.27亿元）为主；总功能价值达12.97亿元，是同期万全镇GDP（8.88亿元）的1.46倍.与2002年相比，2009年研究区各项生态系统功能价值均下降，其中气候调节功能和涵养水源功能的降幅最多；政策情景和保护情景下，各项生态系统功能价值的增减趋势基本一致，除释氧功能和营养元素循环功能价值表现为下降外，其他功能价值均明显增加，但保护情景下研究区生态系统功能总价值的增量高于政策情景，尤其是涵养水源功能和固碳功能.保护情景是研究区社会经济可持续发展的最优管理模式.

| Abstract: | Through the evaluation of the gains and losses of the key functions of regional ecological system under different management modes, various ecosystems functions and their spatial distribution patterns in Wanquan Town were analyzed. Based on different development needs, various scenarios were established and weighed. In 2009, the support function value supplied by the ecosystems in the Town was 58 million RMB, among which, oxygen release function ranked first (37 million RMB), and the regulation function value provided by the ecosystems was 1238 million RMB, among which, climate regulation ranked first (1127 million RMB). The total ecosystem services value was 1297 million RMB, being 1.46 times of the local GDP (888 million RMB) in the same year. Compared with that in 2002, the service function value of the ecosystems declined in 2009, with the largest decrements in climate regulation and water yield. Under policy scenario and protection scenario, the variation trends of the values of various ecosystems functions were basically the same. Except that the values of the functions oxygen release and nutrient cycling decreased, the values of the others increased obviously. Under protection scenario, the total ecosystem services value had a higher increment than that under policy scenario, especially for the water yield and carbon sequestration functions. It was suggested that protection scenario could be the optimal land use management mode for the socio-economic sustainable development of the Town. |
