新疆布尔津县土地利用格局特征研究

基于RS与GIS技术，利用景观生态学理论及景观格局指数对布尔津县土地利用现状进行定量分析。结果显示为：（1）布尔津县以草地、林地为主要景观类型，镶嵌着耕地、水域等景观类型。（2）四个分区（即高山区、丘陵区、平原区、荒漠区）的林地资源组成差异明显，耕地、居民、交通及工矿用地集中分布在丘陵区和平原区（3）从各项指数来看，高山区的多样性指数较低；平原区是受人文因素最多的区域，景观优势度低，各种土地利用类型比例差异不大，有利于生态可持续发展，但要合理的开发利用；荒漠区生态环境相对脆弱，要加强生态环境的保护与改善。通过该研究对布尔津县的土地利用现状作一个了解，为该县乃至整个地区的景观规划和可持续发展战略提供科学依据。

Landuse Patch of Characteristics of Burqin County of Xinjiang

based on RS and GIS，using the theory of landscape ecology and landscape pattern index , this study investigates the Landscape condition of Burqin region in xinjiang .The result shows that（1）the region distributes majority of grassland and forested area, insetting some farmland and water etc. ⑵Thispaper divides the region into four sections to compare their differences between them (high mountainarea, bill area, field, desert); forest resource of sectiong have differences in the types ; farmland and villages mainly lies in field and bill area. ⑶ Showing these index, smallest diversity index of high mountain area is smallest ; artificial factors resulted in dominance index, the percentage of landusetypes have little difference; this have advantage of development of ecology, unless rationally using; in desert, needs to enhance environment protection and improvement. By studying, we know the condition of landuse in Burqin region, the result offer science basis for Landscape planning and ecological sustainable development.
