摘要
从县域尺度对桃江县耕地空间布局、作物种植结构等方面进行研究,为不同地区的耕地结构优化研究提供案例,可以完善耕地结构优化框架体系,同时桃江县作为经济欠发达县城,研究结果可以为我国广大同类地区耕地结构优化研究提供借鉴和参考,有重要的理论意义。开展县域尺度耕地结构优化研究,研究耕地综合生产能力,探索耕地资源最优配置,分析耕地结构优化的经济、社会和生态效益,对合理利用耕地资源,为区域耕地的动态平衡与区域调控,实现区域耕地的可持续利用,特别是对农业优势地区的耕地可持续发展,以及协调好耕地保护与经济发展之间的关系有着重要的实践意义。
Study on the spatial distribution of Taojiang land and crop planting structure from county scale to provide cases for structure optimization of arable land, it can improve optimization framework of arable land ,at the same time,Taojiang is a less developed County, the result of this paper can provide references for the similar areas, there are important theoretical significance. There is important practical significance to carry out structure optimization of arable land and study the overall production capacity of land and explore optimal allocation of land resources and so on. Taojiang is an agricultural county depending on agriculture and rural economy, cultivated land plays a decisive role in economic development.There is important practical significance to research the structure optimization of arable land in this area. Research results will provide policy recommendations and protection for the rational use and protection of cultivated land resources.
