Temporal and Spatial Variation and Match Pattern of Agricultural Land and Water Resources in Hen'an Province
摘要
Abstract
Water and land resources are the core resources for human being,and their spatial distributions have the significant impact on regional grain production and sustainable utilization of cultivated land.He'nan Province is one of major grain product areas in China.We aimed to reveal the spatial matching status of water and land resource of 18 cities in He'nan Province from 1999 to 2013 by using water and soil resources matching model.The results showed that:(1) the cultivated land was 19％ higher in 2013 than in 1999,and the water consumption for agricultural was 13％ lower in 1999 compared with 2013;He'nan Province was rich in cultivated land,while water resource was relatively poor,so the water and soil resources were mismatched;(2) There was a spatial mismatch between water and land resources,the southern and eastern He'nan had major cultivated land,however,the northern and southern He'nan had major water resources;(3) the matching coefficient of water and land resources was 2.1 × 103m3/hm2,which was far below the national average level (5.6 × 103m3/hm2);(4) the matching level gradually deteriorated from the northern and southern boundaries of He'nan to the middle of the area,north He'nan was optimal and east and west He'nan took the middle place which was better than central and west He'nan.For water and land resources matching conditions,only 6 ％ of He'nan covered the good level while 76％ of He'nan showed poor level or even poorer.Therefore,the shortage of water resources was the main limiting factor for the agriculture development in He'nan Province.To against the distinct regional diversity of water and land resources,constructing water conservancy works,comprehensive agricultural water saving technology and optimizing water distribution should be involved and applied.关键词
