【摘要】：针对水资源本身的模糊性和不确定性,基于模糊数学综合评价模型,从水量、水质、人口、社会经济和生态环境5个方面选取18个评价指标,结合AHP法与熵权法确定指标权重,对张掖市2010-2014年的水资源价格进行动态评价,水价计算模糊数学模型由水资源价值评价和水资源价格计算两部分组成.结果表明:采用水资源价值模糊综合指数对水资源价值进行测算,5 a间张掖市水资源模糊综合指数介于水资源价值指数的"中等"与"偏低"之间,说明张掖市水资源价值属于中等偏低;在2010-2014年5 a间水资源价格呈明显上升趋势,核算期初的2010年为2.12元·m~(-3),证实了张掖市目前水资源价格偏低,水资源资产价格存在较大的上升空间,而核算期末的2014年最高达4.96元·m~(-3).基于熵权与AHP相结合确定权重的水资源价格模糊数学综合评价模型,评价结果更客观合理,为下一步水资产负债表编制中水资产与负债价值核算提供数据支持.
[Abstract]:In view of the fuzziness and uncertainty of water resources, 18 evaluation indexes were selected from 5 aspects of water quantity, water quality, population, social economy and ecological environment based on fuzzy mathematics comprehensive evaluation model. Combined with AHP method and entropy weight method to determine the index weight, the dynamic evaluation of water resources price in Zhangye City from 2010 to 2014 was carried out. The fuzzy mathematical model of water price calculation is composed of two parts: water resources value evaluation and water resources price calculation. The results show that the water resources value is measured by the fuzzy comprehensive index of water resources value. 5. The fuzzy comprehensive index of water resources in Zhangye city is between "middle" and "low" of water resources value index, which indicates that the water resources value of Zhangye city is on the low side. The price of water resources increased obviously in the period of 2010-2014, and it was 2.12 yuan 路m ~ (-1) on 2010 in the beginning of accounting period, which confirmed that the water resources price of Zhangye City was on the low side at present. The price of water resources assets has a great space to rise. The maximum value of water resources price is 4.96 yuan 路m ~ (-1) in 2014 at the end of accounting period. The fuzzy mathematics comprehensive evaluation model of water resources price based on entropy weight combined with AHP is more objective and reasonable. For the next water balance sheet compilation of water assets and liabilities value accounting to provide data support.
