A Study on Landscape Patterns Discrepancy in Arid Oasis City Based on GIS——Taking Shihezi City as Illustration
The research of the spatial structure and change trend of land use has become hotspots for LUCC research in international organtions such as IGBP、HDP and WCRP.In order to study the urban structure's change characteristics,we explored the change direction and characteristics of landscape by using the method of landscape ecolopy based on softwares GIS and Fragstats during 1999 to 2009.The results showed that:(1)70％ of the land use wasn't change,and landscape structure changed from natural landscape to urban landscape.(2)Construction land was the largest increases of 19.64 km2,cultivate land was the largest reduce of 17.25 km2.(3) Construction land sprawled with residential area center,and pushed to north and east along the traffic line to the city.(4) Each landscape index of study area was generally higher than its street partition,Xincheng street and Xiangyang street showed a regular shape and a better integrity with a good town planing.This study provides a quantify basis for the change of the urban landuse structure in a scientific measurement,and helps to find significant rules in chaotic landscape,and provide some basis for valuation and optimization of regional landscape patpern,as well as construction,management and design for city in future.
