【摘要】：效益评估是雨水资源化利用的重要基础性工作。采用指标体系法,综合考虑了雨水资源化利用的供给侧约束和需求侧约束两个方面,选用多年平均降雨量、降雨集中度和城市缺水程度3个指标因子,对全国661个城市雨水资源化利用的效益进行了评估,并重点对雨水资源化利用效益的空间差异性进行了分析。结果表明,我国雨水资源化利用的高效益区主要分布于广东省南部地区和海南省;较高效益区主要分布于广东省、安徽省北部、辽宁省北部、河南省东部和京津冀地区;中等效益区和较低效益区在空间分布上较为分散,但总体上以中东部地区为主;低效益区城市主要分布于我国的西北地区(西北五省)、西藏藏族自治区、吉林省和我国南方地区。
[Abstract]:Benefit evaluation is an important basic work in the utilization of resources by Rain Water. By using the index system method, the supply-side constraints and demand-side constraints of Rain Water resource utilization are comprehensively considered, and the annual average rainfall is chosen. Three index factors, rainfall concentration degree and urban water shortage degree, are used to evaluate the benefit of Rain Water resource utilization in 661 cities in China, and the spatial difference of Rain Water resource utilization benefit is analyzed emphatically. The results show that: 1. The high benefit areas of Rain Water are mainly distributed in the southern part of Guangdong Province and Hainan Province, and the higher benefit areas are mainly in Guangdong Province, the northern part of Anhui Province, the north of Liaoning Province, the east of Henan Province and the area of Beijing-Tianjin-Hebei Province. The spatial distribution of middle and lower benefit areas is relatively scattered, but generally the central and eastern regions are the main ones, and the cities in the low benefit areas are mainly distributed in the northwest of China (five provinces in northwest China, Tibet Tibetan Autonomous region, Tibet Autonomous region). Jilin Province and southern China.
