摘要: 以河南省为例,从自然资源持续性、经济社会可行性、生态环境合理性3个方面构建水土资源持续利用评价指标体系,采用三角模型定量分析2000—2014年河南省水土资源持续利用状态及趋势,并在此基础上通过灰色关联分析识别影响水土资源持续利用的主要因素。研究表明:2000—2014年河南省水土资源持续利用状态总体水平不高,在一般持续状态和弱持续状态之间徘徊,其中,2000—2002年呈T6趋势(弱持续),2002—2004年呈T3趋势(一般持续),2004—2010年呈T1趋势(一般持续),2010—2014年呈T6趋势(弱持续)。制约河南省水土资源持续利用水平提升的主要因素多数来源于生态环境系统和经济社会系统,主要包括植被覆盖度、耕地有效灌溉率、人口密度、地均农药施用量和水土流失治理率等。

Abstract: In the present study, land and water sustainable utilization state and trend in Henan Province in 2000-2014 was evaluated by triangle model from 3 aspects of natural resource sustainability, economic society feasibility and ecological environment reasonability. The main influence factors were further identified by grey relational analysis. It was shown that the total level of the utilization was not high, around the fair sustained state and the weak sustained state. The state exhibited 4 obvious trends: T6 trend (weak sustained state) from 2000 to 2002, T3 trend (fair sustained state) from 2002 to 2004, T1 trend (fair sustained state) from 2004 to 2010, T6 trend (weak sustained state) from 2010 to 2014. Factors constraining the promotion of utilization level were mainly from ecological environment system and economic society system. The influence factors included vegetation coverage, effective irrigation rate of cultivated land, population density, pesticides input per hectare and improvement rate of soil and water loss.

Key words: land and water resources, sustainable utilization, triangle model, grey relational analysis, Henan Province
