摘要:

基于土地利用变化以及生态系统服务功能的理论研究, 对河北省张家口市1990, 2000和2008年的生态服务价值进行估算, 探讨土地利用对生态服务功能的影响。结果表明: 张家口市土地利用类型以耕地、草地和林地为主, 草地面积减少和建设用地面积增加幅度较大。不同土地类型产生的生态系统服务价值从大到小依次为林地、耕地、草地、水域、湿地, 其中林地、耕地、草地产生的价值之和约占总价值的90%。生态系统服务总价值在1990—2008 年总体上呈下降趋势, 尤其2000—2008年减少幅度显著, 其中草地、湿地的减幅最大。在各项生态系统服务功能中, 价值结构变化不大, 1990—2000年气候调节的服务价值显著减少, 原材料和水源涵养的服务价值增加幅度较大; 2000—2008年由于湿地和耕地面积的增加, 尤其是湿地面积的增加, 气候调节和食物生产的服务价值随之增加, 其他服务功能价值均减少。

Abstract:

Based on land use data in 1990, 2000 and 2008, and previous theoretical research on land use and ecosystem service value, the authors estimated the ecosystem service value of this three years in Zhangjiakou City and examined the effects of land use change on ecosystem services value, in order to provide useful references for city development planning. Results indicated that the main land use types of Zhangjiakou are farmland, grassland and woodland, grassland decreased and construction land increased significantly. Ecosystem service value of different land use types are sorted in a descending order: woodland, farmland, grassland, water body and wetland; woodland, farmland and grassland contributed about 90% of the total service value. The total ecosystem service value of land use from 1990 to 2008 was on a declining curve, which was mainly due to the decrease in grassland and wetland. As for the service value of single service function, from 1990 to 2000, climate regulation decreased obviously, while raw material and water supply increased significantly; from 2000 to 2008, only climate regulation and food production’s service value increased.

Key words: land use, ecosystem, ecosystem service values, Zhangjiakou
