哈尔滨市土地利用研究
Research on Land Use in Harbin City

土地利用变化特征对开展城市发展规划和确保可持续发展具有重要意义，为了解哈尔滨市在经济快速发展背景下的土地利用变化情况，文章利用Landsat遥感影像对哈尔滨市20年间土地利用变化情况进行研究，基于哈尔滨市2000年、2005年、2010年、2015年、2020年五期30米土地覆盖数据，运用动态度，土地利用转移矩阵，土地利用程度等方法，对哈尔滨市的土地利用情况进行分析。研究结果表明，哈尔滨市建设用地面积不断增加，总体建设程度中等，水域向未利用地转换频繁，林地与耕地为主要土地利用类型，面积占比稳定。
The characteristics of land use change are of great significance for carrying out urban development planning and ensuring sustainable development. In order to understand the land use change situation in Harbin City under the background of rapid economic development, this article uses Landsat remote sensing images to study the land use change situation in Harbin City over the past 20 years. Based on five periods of 30 meter land cover data in Harbin City from 2000, 2005, 2010, 2015, and 2020, dynamic degree is used, This article analyzes the land use situation in Harbin City using methods such as land use transfer matrix and land use degree. The research results indicate that the construction land area in Harbin City is continuously increasing, with an overall moderate level of construction. The conversion of water bodies to unused land is frequent, and forest and cultivated land are the main types of land use, with a stable proportion of area.
