摘要:

本文以内蒙古退耕还林典型县卓资县为研究对象,根据1999年和2007年2期TM影像资料和其它辅助资料,分析了卓资县土地利用变化、区域差异特征和各类型之间的转化情况,并利用马尔可夫模型对2015年土地利用动态变化趋势进行预测研究。结果表明:内蒙古卓资县1999-2007年,因为退耕还林工程的实施,林地和草地的面积有较大幅度增加,分别增长了2.28%和2.85%;耕地和水域面积有较大幅度降低,分别减少了5.88%和1.49%;可以看出林地,草地和耕地是本地区土地利用变化的主导类型,与其他土地利用类型间的相互转化较广。到2015年草地持续增加,将增长2.76%;林地和耕地面积降低,将分减少2.34和6.04%;林地,草地和耕地始终为主要的转化类型,占据主导地位,因此合理利用与保护该区的耕地、林地和草地资源,是该区生态环境建设的必要途径。

Abstract:

Based on the typical county of returning farmland to forest of Zhuozi county in Inner Mongolia as the research object, according to the two periods of the 1999 and 2007’s TM images and other auxiliary materials, this paper analysised the change of land use, regional difference and the conversion between various types ,and used markov model to predict the dynamic change trend of the land use in 2015. The results showed that: the Zhuozi county in Inner Mongolia in the period of 1999-2007, the forest land and grassland were greatly increased 2.28% and 2.85% respectively for the implementation of the returning farmland to forest project. Cultivated land and waters were greatly reduced, and reduced 5.88% and 1.49% respectively. From the result we can see the cultivated land, forest land and grassland were the dominant types of land use change in this area, and they had widely mutual transformation with other types of land use. By 2015, the grassland will be increased 2.76%. Forest land and cultivated area will be reduced by 2.34% and 6.04%. Forest land , cultivated land and grassland are always the dominant types of land use change ,which are the dominant position, therefore, reasonable using and protecting the forest land, grassland and cultivated land resource are the necessary way to construct the ecological environment in Zhuozi county.
