摘要
本研究采用统计分析与遥感判读相结合的方法,对下辽河平原区典型区域耕地利用变化进行研究。结果表明:耕地是研究区域主要土地利用类型,耕地分布比较集中,总体分布不均衡,其中生态退耕、建设用地占用、灾毁和农业产业结构调整是耕地减少的主要原因,对于林地的开垦、未利用土地开发、居民点及工矿用地和水利设施用地整理是耕地增加的主要来源,但耕地总体是逐年减少的。本文提出要处理好耕地保护与粮食安全、城市发展和生态环境建设之间的关系,具体可以通过提高耕地质量保证粮食安全;通过建立城乡统一的土地市场,协调城市化和耕地减少之间的矛盾;通过合理的生态退耕,协调生态环境建设与耕地保护之间的关系。
This study analysis the cultivated land use change in the typical region of the lowerreaches of the Liaohe River Plain by used the statistical analysis and interpretation of the combination of remote sensing methods.The results show that cultivated land is the main land use types in the study area, land distribution is concentrated, the overall distribution is uneven, the ecological restoration, construction land, disaster damage, and agricultural industry is the main reason of the reduction of cultivated land, the reclamation of forest land, residential and industrial land and farmland water conservancy facilities, unused land development is the main source of increase, but the general is decreasing year by year.Proposed for the protection and development of the cultivated land, we should properly handle the relationship between the protection of farmland and food security, urban development and the ecological environment, specific measures are that improving the quality of cultivated land, ensure food security, the establishment of a unified land market, coordination the conflicts between urbanization and reduction of the cultivated land, through reasonable ecological restoration, coordination the relationship between ecological environment construction and cultivated land protection.
