根据景观格局指标体系,从景观类型组成、斑块特征和景观异质性3个方面,对喀什市城市土地景观进行分析.结果表明：1对于城市土地景观格局,林地和耕地是喀什市主要的景观类型,构成了区域的景观优势,是调控城市土地格局稳定性的主要组成部分.2城市土地景观整体格局中耕地占优势,斑块相对均匀,对景观总体空间格局影响较大.从总体来看,景观多样性复杂,优势度和均匀度明显,具有较高异质性.3通过区域城市土地分析发现喀什市城市土地景观整体上具有明显差异.市外的耕地,林地区域有最高的景观变化特征,市区城市土地景观变化较低,主要是景观结构方面的斑块多样性低,景观类型单一.研究结果可为喀什市合理规划和利用土地资源,保护城市环境,促进绿洲城市可持续发展政策制定提供参考.

英文摘要：

According to the landscape pattern index system,the paper analyzes the land landscape in Kashgar city from 3 aspects： landscape type,patch characteristics and landscape heterogeneity. The results showed that：the main landscape types of urban land landscape pattern,forest land and cultivated land are the main landscape types in Kashgar City,which constituted the main part of the stability of urban land pattern. The city landscape in the overall pattern of cultivation to the dominant,relatively uniform patches,had great influence on the overall landscape spatial pattern. From the overall perspective,the landscape diversity,dominance and evenness were obvious,which revealed its heterogeneity. Through the analysis of other regional urban land,the land landscape of Kashgar city was found to be obviously different. Outside of cultivated land and woodland regions with the highest landscape characteristics,urban land landscape changes was low,due to the low diversity of the landscape structure of plaque and singleness in landscape type. These findings can serve as a reference for rational planning and utilization of land resources,protecting the urban environment,and promoting the sustainable development of the oasis city in Kashgar city.
