摘要
为促进河南省水土资源优化配置和协调发展,构建了水资源压力与耕地利用效益评价体系,运用耦合协调度模型评价二者的耦合关系.结果表明:(1)河南省耕地利用效益发展态势较好但增速不同,水资源压力区域差异较大且整体呈现波动增长趋势.(2)河南省耕地利用效益增长导致水资源压力不断增长,二者具有正相关性,且水资源压力波动幅度相对较大.(3)河南省耕地利用效益与水资源压力耦合度从低水平耦合发展到磨合阶段,耦合协调度则从中度失调发展到低度耦合协调.(4)河南省18市耕地利用效益与水资源压力的耦合协调度均呈增长趋势,但增长幅度不同且区域差异较小.
In order to promote the optimal allocation and coordinated development of water and soil resources in Henan Province,the evaluation system of water resource pressure and cultivated land use benefit was constructed,and the coupling relationship between them was evaluated by using the coupling coordination degree model. The results show that:(1) The development trend of cultivated land use benefit in Henan Province is good,but the increase degree is different. The regional difference of water resource pressure is large,and the overall trend is fluctuating and increasing;(2) The increase of cultivated land use efficiency in Henan Province leads to the continuous growth of water resource pressure,which has a positive correlation,and the fluctuation range of water resource pressure is relatively large;(3)The coupling degree between cultivated land use efficiency and water resource pressure in Henan Province has developed from low-level coupling to running-in stage,and the coupling coordination degree has developed from moderate imbalance to low-level coupling coordination;(4)The coupling coordination degree of cultivated land use efficiency and water resource pressure in 18 cities of Henan Province shows an increasing trend,but the growth range is different and the regional difference is small.
