| 摘 要： | 土地利用适宜性对于土地利用规划和管理具有重要的现实意义。本文基于栅格数据,以黑龙江省嫩江县为研究区,利用在高程、坡度、坡向方面的分布特征,采用层次分析法确定指标权重,通过模糊综合评价法对已确定权值的指标进行综合评价。研究结果表明,研究区土地利用主要分为宜农区和宜林区,宜农区中中度宜农区所占比例最大,宜林区中中度宜林区所占比例最大,研究区土地利用适宜性分布具有明显的空间特征。

| Abstract: | It has important practical significance of land use suitability for land use planning and management.Based on raster data to Nenjiang County in Heilongjiang province as the research area, using in elevation, gradient, slope direction distribution characteristics, using analytic hierarchy process (ahp) to determine index weight, through the fuzzy comprehensive evaluation method for the comprehensive evaluation to determine the weights of indexes, the results show that the main land use in the study area is divided into two district: suitable for farmland and suitable for forest.In suitable for farmland district, the largest proportion is the medium area.In suitable for forest area, the largest proportion is the medium area too.The study area land use suitability distribution has obvious spatial characteristics. |
