基于遥感影像的青冈县近20年土地利用变化及影响因素分析
Analysis of Land Use Change and Influencing Factors in Qinggang County in Recent 20 Years Based on Remote Sensing Images

随着人类社会的高度发展，原有土地资源所提供的物质资源和空间资源，已经无法满足人类为了追求更好的、更优越的生活条件所提出的要求，因此原有的土地资源平衡被打破，生态平衡遭到了破坏，人类生活环境和可持续发展能力受到严重的影响。本研究采用2015、2005以及1995遥感影像对青冈县进行土地利用变化监测。研究结果表明研究区域最主要的土地利用类型有耕地、林地、草地、水域、建设用地和未利用地6大类。在过去近20年间，随着总人口数以及非农业人口数的增加和经济发展，各种土地利用类型面积在20年间都发生了不同程度的变化，水域、林地、草地、建设用地的面积是呈现增加趋势的；而耕地和未利用地的面积是呈减少的趋势。本文对青冈县的土地利用变化情况进行了分析，可为今后青冈县土地资源的合理规划以及开发提供可靠依据。
With the high development of human society, the material resources and space resources provided by the original land resources can no longer meet the requirements of human beings in pursuit of better and superior living conditions, so the original land resource balance has been broken, the ecological balance has been disrupted, and the human living environment and sustainable development capabilities have been seriously affected. This study used 2015, 2005 and 1995 remote sensing images to monitor land use change in Qinggang County. The research results indicate that the main types of land use in the study area are cultivated land, forest land, grassland, water area, construction land and unused land. In the past 20 years, with the increase of the total population and non-agricultural population and economic development, the area of various land use types has changed in different degrees during the past 20 years, and the area of water, forest, grassland and construction land is showing an increasing trend. This paper analyzes the land use changes in Qinggang County, which can provide a reliable basis for the rational planning and development of land resources in Qinggang County in the future.
