基于地表覆盖数据的农业水土资源匹配格局分析——以辽宁省为例
|
摘要
针对如何更加合理利用水土资源以提高粮食产量的问题,基于地理国情监测获得的地表覆盖数据和粮食产量统计数据,从微观角度反映水土匹配对粮食产量的影响。以我国东北地区重要粮食主产区辽宁省为研究对象的数据显示,辽宁省水土匹配状况空间分布不均匀现象明显,中部地区优于东西部地区,东部地区优于西部地区;粮食产量中部地区高于东、西部地区,西部地区高于东部地区。研究结果表明,辽宁省水土匹配系数较高的地区与粮食产量较高的地区均分布在辽宁省中部地区,但东西部地区水土匹配与粮食产量存在空间错位,建议在中部地区保护水资源,东部地区根据地形条件选择适宜农作物种植,西部地区兴修水利,改善水土匹配状况,提高粮食产量。
In view of how to make more rational use of water and soil resources to improve food production,based on the geographical coverage data and grain output statistics obtained from the monitoring of geographical conditions,this paper reflects the impact of soil and water matching on grain yield from a micro perspective.According to the data of Liaoning province,an important grain producing area in Northeast China,the spatial distribution of water and soil matching in Liaoning province is uneven.Among them,the central region is superior to the eastern and western regions,and the eastern region is superior to the western region;besides,the grain output in the central region is higher than that in the eastern and western regions,and the western region is higher than the eastern region.The results show that the areas with high water and soil matching coefficient and high grain yield are located in the central part of Liaoning province,but there is spatial dislocation between soil and water matching and grain yield in the eastern and western regions.It is recommended to protect water resources in the center region.In the eastern region,suitable crops are selected according to the topographical conditions,water resources are supposed to be improved in the western region,so as to make water and soil matching conditions and grain yield better.
