摘要:
根据1992-2001年土地利用详查数据，分析陕北黄土高原这一典型地区的土地利用时空变化特征，揭示该区土地利用的数量变化、空间变化和变化趋势。研究表明：陕北黄土高原土地利用变化较大，其中以园地变化最大；土地利用变化的空间差异明显，并与其自然地理分区基本吻合，由北至南呈现低-高-低-高的趋势；9 a来陕北黄土高原土地利用处于调整期，利用方式日趋无序。
Abstract:
Based on detailed survey data of land use from 1992 to 2001,using dynamic degree model,change of land use degree model and change of information entropy model,this paper analyzed the land use spatial-temporal changes and the change trend in Loess Plateau of Northern Shaanxi province.The conclusions were drawn as follows:(1) land use changed observably.Farmland and unused land reduced.Meantime,forest land,garden land,grassland,rural residential land and city and town land,traffic land and waters land increased.The synthetic dynamic degree of land use in Loess Plateau of Northern Shaanxi province is 0.83% per year.The conversion rate of Garden land is 35.10%,the biggest number of all land use types.(2) The spatial difference of land use change was obvious.The distribution of spatial difference was in reasonable agreement with physical geography subarea.The trend from north to south presented low-high-low-high.(3) The change of land use degree and information entropy indicated the alterative trend of land use.Both of the change showed that in the last 9 years the land use type was inordinate gradually.
