Characteristics of Landscape Pattern of Land Use in Korla City Based on Moving Window Method
摘要
Abstract
The oasis city is the center of human production and life in the arid area.As an oasis city,the man-land relationship in Korla City is equally sensitive.Understanding the spatiotemporal evolution of land use landscape pattern is of great significance for improving the man-land relationship and ecological securi-ty in the region as well as promoting high-quality development.This paper used the principles of landscape ecology to analyze the land use landscape pattern of Korla City from the perspective of landscape level and category according to various landscape parameters.The geographic detector was adopted to analyze the driving forces.The results showed that 1)unused land was still the main body of the landscape.2)The transfer characteristics of landscape types were mainly reflected in the conversion between landscape area and types,and there were significant spatiotemporal and changes.3)Patch density(PD),number of pat-ches(NP),Shannon's division index(SHDI)and Shannon's evenness index(SHEI)gradually increased;Contagion index(CONTAG)decreased,division index(DIV)increased,the degree of fragmentation be-tween urban and suburban areas was increasing,the impact of human activities continued to increase,the level of urbanization increased,and Korla was in a period of rapid development.4)Normalized difference vegetation index(NDVI)was the dominant factor influencing the spatiotemporal variations,manifested by its highest contribution rate.According to the interactive factor detection results,when NDVI reacted with precipitation and temperature,it had stronger explanatory power.The annual average temperature change and precipitation were generally in a fluctuating and rising stage.The study of landscape fragmentation pat-tern is conducive to understanding the changing law of landscape pattern in the rapid growth stage of large cities,and provides a basis for urban habitat protection and ecological function restoration.关键词
