陕西省丹汉江流域土地利用时空变化动态分析
Temporal-Spatial Land Use Change of Danjiang and Hanjiang River Watershed in Shaanxi Province
摘要
Abstract
Based on the three sets of LUCC data（1985,1995 and 2000） from the Environmental and Ecological Scientific Data Center of West China,spatial analysis with GIS and statistics methods were applied to analyze the quantitative change,transferring status,and transferring rate of land use types in Danjiang and Hanjiang river.The spatial distributions and the dynamic changes of land use were also studied in regard to different slopes.The results indicate that cultivated land,forest and grassland were the main land use types in the study area,accounting for more than 99% of the total area.From 1985 to 2000,the areas of cultivated land,forest,architecture and water deceased and then increased,as the grass land showed the opposite trend.Cultivated land and architecture land increased 105.08 km2 and 14.85 km2 respectively,forest and grass land decreased 41.02 km2 and 77.63 km2 respectively during the fifteen years.In terms of slopes,the land use change mainly occurred on the lands with slopes from 5° to 35°,and the land with slope from 15° to 25° experienced the greatest change.关键词
