摘要:
 确定右玉县景观脆弱度,通过景观脆弱度来反映景观生态系统受到的干扰程度。以山西省右玉县为例,在建立景观脆弱度指数的基础上,通过GS+软件进行变异函数拟合分析和ARCGIS 10.2的普通克里格插值,得到景观脆弱度分布图,利用GeoDa软件分析景观脆弱度的空间自相关格局。结果表明,研究区的景观类型以耕地和林地为主,耕地、水域和未利用地面积呈下降趋势,林地、草地、城镇用地和工矿用地面积呈减少趋势;在实施退耕还林还草、发展生态旅游政策的影响下,研究区景观的多样性有所增加,景观脆弱度呈下降趋势,生态环境呈现正向演替,景观脆弱度在空间上是正相关的,且正相关趋势随着时间在增强。研究结果可为右玉县土地可持续利用提供决策依据,同时也可为类似地区景观脆弱度分析提供参考。
Abstract:
 The purpose of this paper was to determine the fragility of landscape in Youyu County,Shanxi Province and to reflect the degree of disturbance of landscape ecosystem.Based on the establishment of the indices of landscape vulnerability,the distribution of landscape fragility was obtained by fitting the variation function with GS+and establishing the ordinary Kriging interpolation with ARCGIS 10.2 in Youyu County.The spatial autocorrelation pattern of landscape vulnerability was analyzed by GeoDa.The results showed that the landscape types of the study area were mainly cultivated land and forest land,and the areas of cultivated land,water and unused land decreased,and the areas of forest land,grassland,urban land,industrial and mining land decreased.Under the influence of returning farmland to forest and grassland and developing eco-tourism,the diversity of the landscape in the study area increased,and landscape vulnerability reduced,and the ecological environment in the good direction of development.Landscape fragility was positively correlated to the space,and positive correlation trends increased with time.The results could provide the basis for the sustainable use of land in Youyu County,also provide reference for the analysis of landscape vulnerability in similar areas.
