| 摘 要： | 目的]土地利用是影响水土流失变化的重要因子,通过分析准格尔旗土地利用类型动态变化情况,掌握该区各土地利用类型变化去向,为分析该区水土流失状况提供依据。方法]采用土地利用转移矩阵方法研究准格尔旗土地利用变化特征。结果]2014—2016年,准格尔旗各土地利用类型变化不显著,表现为林地、草地、水域及水利设施用地占地面积分别减少16.02,12.66和2.48km^2,居民点及工矿交通用地、其他土地、耕地的占地面积分别增加18.63,10.53和1.72km^2;该区水土流失面积增加70.8km^2。结论]准格尔旗减少的林地和草地主要转变为居民点及工矿交通用地和其他土地。结合水土流失数据分析表明,该区域水土流失面积的增加与林地和草地面积减少,以及林地和草地植被覆盖度的变化有关。

| Abstract: | Objective] Land use structure is an important factor affecting soil erosion. By analyzing the dynamics of land use in Jungar Banner, we aim to understand the trend of land use change and provide basic data for soil erosion analysis in this area.Methods] The transfer matrix of land use was used to study the land use change in Jungar Banner.Results] The land use change in Jungar Banner was not significant between 2014 and 2016. Woodland, grassland, water area and land for water conservancy facilities decreased by 16.02, 12.66 and 2.48 km2, respectively. The land for residential, industrial, mining and transportation use, other land (sandy land and bare rock) and cropland increased by 18.63, 10.53 and 1.72 km2, respectively. The soil erosion area was increased by 70.8 km2 in this region.Conclusion] The reduced woodlands and grasslands in Jungar Banner are mainly converted into residential-industrial-mining-transportation land use and other land use types. Combined with soil erosion data, the increase of soil erosion in this area is mainly related to the decrease of woodland and grassland area, and changes in woodland and grassland coverage. |
