摘要 | 为了客观地评价内蒙古河套灌区农业水土资源时空匹配情况,在分析灌区水土资源利用现状和空间分布格
局的基础上,以灌溉用水量作为水资源量的表征参数,构建了农业水土资源匹配测算模型,评价了河套灌区及5个县
域的农业水土资源匹配程度,并对其匹配程度进行了划分。结果表明:河套灌区农业水土资源匹配一般,耕地资源优
势明显,水资源问题突出;10a来农业水土资源匹配程度逐渐降低,匹配程度空间差异性较为显著,总体呈现出“自西
向东依次变差”的特点。针对河套灌区农业水土资源匹配程度差、区域差异明显的情况,应加强该区水利工程建设和
加快水务管理体制改革,同时兼顾农业水土资源优化配置,提高河套灌区农业水土资源匹配程度。 |
其他摘要 | Abstract:In order to evaluate the spatiotemporal matching situation of agricultural water and land resources
correctly in Hetao Irrigation District,the utilization and spatial distribution pattern of the water and land
resources were analyzed,and the amount of irrigation water was introduced into the study as the characteristic
parameter of water resources quantity,and then a measure model for matching patterns was constructed
to evaluate the matching degree of agricultural water and land resources of Hetao Irrigation District and five
county regions in this area,the matching degree was graded finally.The results indicated that the agricultural
water and land resources showed a situation on the whole that land resources were abundant while water
resources were deficient;during the past decade the matching coefficient of agricultural water and land
resources was reducing gradually,and the spatial distribution patterns of the two resources exhibited an obvious
dislocation phenomenon,the characteristic was that the degree was decreasing from west to east.Against
the situation of agricultural water and soil resources in Hetao Irrigation District,strengthening the construction
of water conservancy project,speeding up the water management system reform and optimizing agricultural
soil and water resources configuration should be conducted to increase the degree of agricultural water
and soil resources matching. |
