Ecological Risk Assessment of Rural Landscape of Southern Jiangsu Water Net from the Perspective of"Ecology-Production-Living"Space——A Case Study of Stone Pool Area
摘要
Abstract
The villages in Southern Jiangsu water net are the pioneer areas of new urbanization construction,but the rapid economic construction has caused great interference to the landscape pattern of"ecology-pro-duction-living"space(EPLS),and the changes in landscape ecological risks caused by them are worthy of attention.Taking Stone Pool area of Suzhou as an example,four-period land use data(1990,2000,2010 and 2020)were selected to construct a landscape ecological risk evaluation model based on the landscape pat-tern index,and the spatial and temporal differentiation characteristics of landscape ecological risk in EPLS in the study area were quantitatively analyzed.The results showed that 1)significant changes occurred in the spatial area of EPLS in Stone Pool area from 1990 to 2020.The area of ecological space increased steadi-ly,the area of agricultural production space decreased year by year,and the industrial production space,ur-ban living space and rural living space expanded significantly.The transfer types of EPLS mainly occurred from agricultural production space to urban living space and industrial production space.2)There was a correlation between the EPLS and the landscape ecological risk in the study area,the high-risk area was mainly distributed in the ecological space of Chenghu Lake and other waters,the medium-risk area was mainly the agricultural production space and rural living space distributed around the lake,and the low-risk area was mostly urban living space and industrial production space distributed in clusters.From 1990 to 2020,the ecological risk level of landscape in Stone Pool area continued to rise,and the area of higher and high-risk areas gradually expanded,accounting for 14.43%and 7.50%,respectively.3)There was a signif-icant spatial positive correlation in the landscape ecological risk in Stone Pool area;the spatial distribution of ecological risk index was mainly in high-high and low-low aggregation,and the spatial differentiation characteristics were obvious.关键词
