【摘要】 研究目的:采用生态系统服务功能理论解决土地利用中生态效益的量化问题,从空间上显示生态效益变化的趋势。研究方法:生态系统服务功能价值理论、环境经济学方法、USLE模型、风蚀流失量统计模型。研究结果:研究区伊金霍洛旗1990年与2000年相比生态价值减少约2.1亿元,与经济增长呈相反方向,但是空间分析表明该地区大范围内生态系统服务价值增加,局部地区减少严重。研究结论:生态系统服务价值空间变化更有助于把握生态与经济的平衡点,是土地利用空间布局的有效辅助手段。更多还原

【Abstract】 The purpose of the study is to quantify the ecological benefit of land use and its spatial change on the basis of eco-system service theory.Such methods were applied as ecosystem services theory,environmental economics,USLE and wind erosion statistics model.The results revealed that the total ecosystem services value decreased 2.1×108 Yuan from 1990 to 2000 in Yi Jin Huo Luo County of Inner Mongolia along with local eoconmic growth.Based on spatial analysis,it is found that the ecological value distribution is unbalanced.The spatial change of ecosystem services can be helpful to well balance ecological protection and economic growth and can be an effective tool in spatial allocation of land use.更多还原
