摘    要:针对中国的实际情况,对不同土地利用类型单位面积生态服务价值进行了校正,并以此为基础,计算了自上一轮土地利用规划实施以来(1996~2004年)我国不同省市土地利用变化引起的生态服务功能的变化.结果表明,该时期内全国土地利用变化导致生态服务功能整体增加了0.91%.其中正向变化最大的省份是天津市,其生态服务功能增加了5.69%;负向变化最大的省份是上海市,其生态服务功能下降了9.79%.对不同生态服务类型的变化分析表明,生态服务中气候调节功能增加最快,1996~2004年间全国增加了3.43%;生物资源控制功能下降最快,期间下降了2.26%.研究还认为,引起我国土地生态服务价值变化的主要原因是该时期内全国水域面积和林地面积的增加导致了生态系统服务功能的增加,而城市建设用地和交通用地的增加导致了全国生态服务功能的下降.

关 键 词:土地利用  生态服务价值  环境影响评价

Abstract:The environmental impact of land use change is long-term and cumulative. The ecosystem service change results from land use change. Therefore, the ecosystem service function change is the key object in the environmental impact assessment of land use change. According to the specific situation of China, this paper adjusted the unit ecosystem service value of different land use types. Based on this, the ecosystem service value change of different provinces in China resulted from the land use change since the implementation of the last plan of land use (1997-2010) was analyzed. The results show that the ecosystem service value in China increased 0.91% from 1996 to 2004. Thereinto, Tianjin is the province that the ecosystem service value increased most quickly, which was 5.69% from 1996 to 2004, while Shanghai is the province that the value decreased most quickly, which was 9.79%. Furthermore, the change of 17 types of ecosystem services was analyzed. Among them, the climate regulation function enhanced 3.43% from 1996 to 2004 and the biology resource control was weakened by 2.26% in this period. The results also indicate that the increase of the area of water surface and forest is the main reason for why the ecosystem service value increased in China in that period.
Keywords:land use  ecosystem service value  environmental impact assessment
