土地生态服务价值评价及其在土地利用布局中的应用--以杭州市萧山区为例

土地是一切陆地生态系统的载体，人类的任何经济社会活动都离不开土地；另一方面，人类的土地利用活动也会影响生态系统．从而会影响其生态服务价值。对杭州市萧山区近年来土地利用的生态服务价值及生态服务价值／GDP值的时空分布进行了研究．结果表明：1999～2004年萧山区土地利用的生态服务价值处于增长趋势，但与GDP比值却处于下降趋势；萧山区土地利用生态服务功能价值／GDP值“中间低两端高”的空间分布特点。根据萧山区生态服务价值时空分布特点，将萧山区划分为4个土地利用区，即城区土地利用区、东部土地利用区、东南部土地利用区、南部土地利用区，并提出了不同土地利用区的主要用途。

Evaluation of Land Ecological Service and Its Application in Overall Arrangement of Land Use--A Case Study of Xiaoshan, Hangzhou

On the one hand,land is the carrier of terrestrial eco-system,and it is also the base of all the human social-economic activities;on the other hand,human activities of land use must impact the eco-system,thus affect the value of eco-system service(VES for short).It studied the spatio-temporal distribution of the VES and the VES-GDP ratio in Xiaoshan district,Hangzhou.The result suggested: from 1999 to 2004,the VES presented an increasing trend,but the VES-GDP ratio presented a reversed trend at the same time;for spatial distribution,the VES-GDP ratio is higher in center area then the peripheral area's,and let the plot of which displayed like a hump.According as the spatio-temporal distribution of the VES,the whole Xiaoshan district can be divided into 4 land use areas: urban area,eastern area,southeastern area and southern area,and the suitable use of the land in each area was discussed.
