摘要

[目的] 揭示安徽省生态系统服务价值变化规律

为区域可持续发展提供依据。[方法] 以安徽省3期的土地利用数据为基础

根据研究区不同土地利用类型的单位面积生态服务价值和各土地利用类型面积分别分析了研究区内2000-2010年不同时段的生态系统服务价值、不同土地利用类型生态服务价值变化的贡献率以及不同年份各单项功能生态服务价值。[结果] 研究区林地和耕地是主要的土地利用类型

其次是建设用地和未利用土地;2000

2005

2010年生态服务总价值量分别为:532.31

537.59和531.35亿元;土地利用类型的贡献度从大到小依次为:林地 > 耕地 > 水域 > 草地 > 未利用地 > 建设用地;林地和建设用地是生态系统服务价值变化贡献率最大的土地利用类型;9个单项生态服务价值从大到小依次为:维持生物多样性 > 保持土壤 > 气候调节 > 气体调节 > 原材料生产 > 提供美学景观 > 食物生产 > 废物处理 > 水文调节。[结论] 研究区内的生态服务价值呈现相对稳定态势

其中林地对生态服务总价值的贡献最大

建设用地是生态服务总价值增长的主要牵制力。

Abstract

[Objective] Studying the variation of ecological services value in Anhui Province in order to provide a support for regional sustainable development. [Methods] Three phases of land use data of Anhui Province were used to calculate the ecological service value per unit area of different land use types and their areas. Ecological services value

contribution rate of ecological services value of different land use types resulted from their changes

and ecological service value of each function in different years were respectively analyzed from 2000 to 2010. [Results] The main land use types were forest land and cultivated land

and the following types were construction land and unused land. In 2000

2005

2010

the total values of ecosystem services were 53.231

53.759

53.135 billion yuan

respectively. The contribution of six types of land use ranked as: forest land > cultivated land > water area > grassland > unused land > construction land. Forest land and construction land contributed mostly to the changes of ecosystem services value. Functions of ecological service value were ordered as follows: maintaining biodiversity > keeping soil > climate regulation > gas regulation > raw materials production > providing aesthetic landscape > food production > waste treatment > hydrology regulation. [Conclusion] The ecosystem services value in the study area was stable largely

of which the forest lands had the largest contribution to the ecological services value

and the construction land was the main holdback force of the growth of the ecological services value in the study area.
