【摘要】：近年来黑龙江省挠力河流域工农业有了长足发展,为了合理开发利用和保护地下水资源,基于挠力河流域灌区实际情况,采用主成分分析法和集对分析法,选取耕地灌溉率、地下水开采率、地下水利用率等8个指标,对挠力河流域灌区内现状年地下水资源承载力进行综合分析和评价。结果表明:锦西灌区、东泄总灌区、友谊西部灌区、锦南灌区、大兴灌区、八五三灌区地下水资源开采已经具有一定规模,继续开发的潜力比较小;三环泡灌区、五九七灌区、龙头桥灌区、尖山子灌区、七里沁灌区仍具有一定的开采潜力,可以适当增强地下水的开采力度。并据此进一步提出了提高挠力河流域水资源承载力的对策。研究采用了两种评价方法,以便评价结果能更加合理、可信;同时也证明了集对分析方法应用于地下水资源承载力评价的合理性。
[Abstract]:In recent years, the industry and agriculture of Nailihe River Basin in Heilongjiang Province have made great progress. In order to develop and protect groundwater resources reasonably, based on the actual situation of the irrigation area of Niuli River Basin, principal component analysis method and set pair analysis method are used to select the irrigation rate of cultivated land.Eight indexes, such as groundwater exploitation rate and groundwater utilization rate, were comprehensively analyzed and evaluated for the carrying capacity of groundwater resources in the irrigation area of Naoli River Basin in the current year.The results show that: the exploitation of groundwater resources in Jinxi Irrigation District, Dongxie General Irrigation District, Yaixi Irrigation District, Jinnan Irrigation District, Daxing Irrigation District, and Baxi Irrigation District already has a certain scale, and the potential for further development is relatively small; Sanhuan Pao Irrigation District, 597 Irrigation District,Longtouqiao Irrigation District, Jianshanzi Irrigation District and Qiliqin Irrigation District still have some potential for exploitation, which can strengthen the exploitation of groundwater.Based on this, the countermeasures to improve the carrying capacity of water resources in Naoli River Basin are put forward.Two evaluation methods are used in this study so that the evaluation results can be more reasonable and reliable, and it is also proved that it is reasonable to apply the set pair analysis method to the assessment of groundwater resources carrying capacity.
