摘要
基于2009—2018年新疆及各地州市水土资源数据,构建水资源压力及耕地利用效益评价模型,并采用耦合协调模型对新疆水资源压力与耕地利用效益耦合关系进行实证研究。研究发现,2009—2018年新疆水资源综合压力呈下降趋势,无人口和经济发展压力,生态和技术发展压力较大;新疆耕地利用社会效益、经济效益呈上升趋势,但生态效益波动幅度较大,受生态效益影响耕地利用综合效益波动较大;10年来新疆水土资源耦合协调度呈上升趋势,但水资源压力综合得分不稳定,耕地利用综合效益相对平稳。新疆水资源技术发展压力大,南北疆耕地利用效益地区差异显著,应加强统筹协调水土资源开发利用,实现水土资源可持续发展。
Based on the water and land resource data of Xinjiang and other prefectures and cities from 2009 to 2018,an evaluation model of water resources pressure and cultivated land utilization benefits was constructed,and a coupling coordination model was used to conduct empirical research on the coupling relationship between water resources pressure and cultivated land utilization benefits in Xinjiang.The research found that the comprehensive pressure on water resources in Xinjiang had shown a downward trendfrom 2009 to 2018,there was no pressure on population and economic development,and there was greater pressure on ecological and technological development;The social and economic benefits of cultivated land use in Xinjiang had shown an upward trend,but the ecological benefits fluctuated greatly,and the comprehensive benefits of cultivated land use fluctuate greatly affected by the ecological benefits;The degree of coupling and coordination of Xinjiang’s water and land resources had shown an upward trend in the past 10 years,but the comprehensive score of water resources pressure was unstable,and the comprehensive benefits of cultivated land use were relatively stable.The pressure on the development of water resources technology in Xinjiang was great,and there were significant differences in the benefits of cultivated land utilization between the north and the south.Therefore,overall planning and coordination of the development and utilization of water and land resources should be strengthened to achieve sustainable development of water and land resources.
