- 摘要:
- 科学合理地利用水资源是缓解我国水资源危机的有效途径，而水资源可持续利用评价是其基本前提，具有重要的研究价值和实际意义。为此，建立了基于熵权的水资源可持续利用模糊综合评价模型，对2003-2016年广西的水资源可持续利用状况进行了评价。结果表明：2007年以前，级别特征值维持在3.6~3.9，处于不可持续利用状态；2008-2011年，级别特征值在3.5上下波动，即波动于不可持续与基本可持续状态；2012年以来，级别特征值稳定在2.5~3.0，处于基本可持续水平状态。尽管如此，还需通过强化水资源管理、提高水资源利用效率、加大污水处理能力和推行节水技术等方式进一步提高广西的水资源可持续利用水平。
- Abstract:
- Scientific and rational utilization of water resources is an efficient path to ease water resources crisis in China. However, water resources sustainable utilization is its fundamental premise, has important research value and practical significance. For this purpose, the fuzzy comprehensive evaluation of water resources sustainable utilization was established based on entropy weight, and the status of water resources sustainable utilization in Guangxi during 2003-2016 was evaluated. The results showed that the water resources were the unsustainable status before 2007 because the level characteristics values were between 3.6~3.9, and fluctuated between the unsustainable and low sustainable status during 2008-2011 because the level characteristics values wobbled around 3.5, but were the low sustainable status after 2012 because the level characteristics values ranged between 2.5~3.0. In order to further enhance the sustainable utilization level of water resources, many ways should be put into practices, such as strengthening water resource management, rising water resource utilization efficiency, improving wastewater treatment capacity and popularizing water saving technology.
