万州区生境质量研究

为找到经济发展和生态保护的平衡点,明确土地利用变化对生态环境产生的影响,以万州区为对象,分析其2009~2014年土地利用变化,采用InVEST模型,创新参数设置和土地利用可达度的确定方法,对区域生境质量进行了研究。结果表明:万州区生境质量总体保持较好。但相比2009年,由于建设用地扩张和脆弱的自然生态,当前生境质量轻微退化,其主要分布于可达度高、人类活动频繁的城镇交通用地周围和地形地势转换的脆弱地带,生境水平较基期降低。

Research of Habitat Quality in Wanzhou District

To find the equilibrium point between economic development and ecological protection,and discern the influences of land use changes on ecological environment,took Wanzhou District as the study area.This paper analyzed local habitat quality change from 2009 to 2014 by utilizing the InVEST model,and proposed methods of setting model parameters and land accessibility.The results showed that the habitat quality of Wanhoukeeps well.But comparing to the year of 2009,the expansion of construction land and vulnerable ecology caused the degradation of the current quality,which concentrate in the high accessibility area,the periphery of center city,terrain transformation of fragile area and along the traffic land.In general,habitat quality levels were lower than the base period.
