【摘要】 基于南四湖流域1990—2015年的土地利用数据,运用回归分析的方法研究了南四湖流域的生态系统服务价值及其变化趋势,以及南四湖生态系统服务价值与国内生产总值、人口以及产业结构的相关关系。研究发现:(1)由于森林等面积的大幅降低,南四湖流域生态系统服务价值呈现降低态势。(2)经济水平稳步上升,但仍相对不发达,高新技术落后,资源利用方式粗放,使生态系统服务价值降低。(3)人口数量多且仍不断增长,使建设用地等土地利用面积大量增加,引起生态价值不断降低。(4)以重工业占据主导地位的"重型"产业结构,对于环境破坏较大,并导致生物多样性降低以及生态系统服务价值的降低。更多还原

【Abstract】 This paper mainly selects the land use data of Nansi Lake Basin from 1900 to 2015 to calculate its ecosystem service value.This study uses regression analysis method to analyze the change trend of ecosystem service value of Nansi Lake Basin.And the study explores the correlation between ecosystem service value of Nansi Lake and GDP,population and industrial structure.The results show that:( 1) The ecosystem service value of the Nansi Lake Basin showes a downward trend due to the sharp decrease of forest and other areas.( 2) The economic level rises steadily,but it is still relatively underdeveloped,and high-tech is backward,and the use of resources is extensive,which reduce the ecosystem service value.( 3) The large and growing population increases the land use area such as construction land,resulting in a decrease in the ecosystem service value.( 4) The "heavy"industrial structure,dominated by heavy industry,causes great damage to the environment,and leads to the reduction of biodiversity and ecosystem service value.更多还原
