摘要
晋陕蒙三省交界地带自然资源丰富,但该区生态环境脆弱,为了缓解该区域开发与治理中存在的突出矛盾,本文以内蒙古准格尔旗为研究区,基于DEM和土壤类型等数据,应用3S技术对准格尔旗高程、坡度和坡向等基本地形特征进行分析,结合全旗土壤类型数据,划分立地类型。结果表明:准格尔旗高程820~1570 m,坡度和坡向变化趋势呈由北向南逐渐增大的规律,针对准格尔旗的地形地貌特征,将该旗土地划分为19个立地类型,在此基础上,结合准格尔旗发展规划,将准格尔旗划分为黄河平原区、风沙区、黄土丘陵区、砒砂岩区,并给出相适宜的人工林空间配置建议,以期为准格尔旗水土流失预报、生态环境修复及社会经济发展提供理论依据和规划建议。
The provincial border region of Shanxi,Shaanxi and Inner Mongolia is rich in natural resources,with fragile ecological environment.In order to release the conspicuous contradictions between regional development and governance,taking Jungar Banner as research region,based on the data of DEM and soil types,the basic terrain features,such as elevation,slope and aspect,have been analyzed by use of 3S technology,and the site types have been divided.The results show that the elevation of Jungar Banner is 820-1570 m,the slope and aspect increase gradually from north to south.According to the topography and landform character in Jungar Banner,the land has been divided into 19 site types.On this basis,combined with the development plan,Jungar Banner is divided into the Yellow River Plain Area,Aeolian Sand Area,Loess Hilly Area and Arsenic Sandstone Area.Meanwhile,the suitable spatial allocation suggestions for plantation are put forward to provide the theoretic basis for the forecast of soil and water loss,restoration of ecoenvironment and social and economic development in Jungar Banner.
