Study on the Change of Landscape Ecological Quality in Xianlin New City of Nanjing
摘要
Abstract
The impact of urbanization on ecological environment is increasingly significant.Discussion on the impact of urban landscape pattern changes on ecological quality becomes one of the most important and fundamental issues.This paper focuses on understanding landscape structure and pattern impact on landscape ecological quality in Nanjing Xianlin New City and a landscape structure-based model integrating stabilization degree and disturbance degree of landscape ecosystem is established.Based on RS and GIS technology,the spatial difference image of each index is constructed to analyze the pattern of landscape ecological quality and their changes at temporal and spatial scale in the context of rapid urbanization in the study area.Evaluation results showed that the disturbance degree increased during 2003 and 2009,the area of level 4 and 5 was increased by 89.34%,and with obvious spatial heterogeneity;and the stabilization degree seriously declined because of rapid urbanization,with a loss of 83.11% of level 4 and 5;as results,the landscape ecological quality became worse than before,the area of level 4 and 5 was decreased by 82.25%,and the declined degree may become more significant in pace with urbanization.Research on evaluation of landscape ecological quality has important meaning for land ecological management and sustainable land use.关键词
