【摘要】：土地利用格局优化对改善区域生态环境和实现土地可持续利用具有重要意义。文章以黑龙江省产粮大县——巴彦县为研究区,运用3S技术,采用Matlab编程,建立土地利用格局元胞自动机优化模型,对2020年研究区土地利用格局进行优化。结果表明:1经本文改进的元胞自动机模型具有较好的土地利用格局优化能力。2土地利用格局优化后,研究区耕地和草地面积减少,林地和建设用地面积增加;从格局变化的环境效应角度出发,耕地面积应控制性的减少,其他用地类型面积适当增加,特别是林地面积亟待大幅提升。3经优化,研究区林地和草地较为集中,建设用地空间分布较为分散,耕地的空间分布大致和现状保持一致;土地利用格局变化的敏感地区主要位于西北部地区和东北部地区;林地、草地、建设用地的变化均直接与耕地的变化相关,土地利用格局的变化具有显著的区域分异特征。
[Abstract]:The optimization of land use pattern is of great significance to the improvement of regional ecological environment and the realization of sustainable land use. This paper takes the grain producing county of Heilongjiang Province-Bayan County as the research area, using 3s technology and Matlab programming. The optimization model of cellular automata for land use pattern was established. This paper optimizes the land use pattern of the study area in 2020. The result shows that the cellular automata model improved by this paper has better ability of land use pattern optimization. 2. After optimizing the land use pattern, the cultivated land and grassland area in the study area are reduced. The area of woodland and construction land increased; from the point of view of the environmental effect of pattern change, the area of cultivated land should be reduced in a controlled way, and the area of other types of land should be appropriately increased, especially, the area of forest land should be improved by 3. 3. In the study area, the forest land and grassland are concentrated, the spatial distribution of construction land is scattered, the spatial distribution of cultivated land is roughly consistent with the present situation; the sensitive areas of land use pattern change are mainly located in the northwest and northeast regions; The change of grassland and construction land is directly related to the change of cultivated land, and the change of land use pattern has significant regional differentiation characteristics.
