四川省水力资源经济可开发量界定的初步研究

Preliminary study on the definition of economic developable kydropower resources Potential in Sichuan Province

我国水力资源蕴藏量位居世界之首，但至今尚未对经济可开发水力资源量进行实质性研究。我国水力资源大省之一的四川省，率先进行了水力资源复查工作，并纳入了经济可开发量的研究。经济可开发量的评估原则是与其他电源相比具有竞争力，采取宏观与微观、定量与定性、精确与模糊相结合的综合分析方法。通过国民经济评价定量测算，四川省的经济可开发水力资源量为１００４５．４７万ｋｗ，５４０２．５８亿ｋＷ·ｈ，分别占全国的３１．２％和４２．６％。

The hydropower potential in China ranks the first in the world, but the economic developable hydropower potential has not been studied up to now. The survey of hydropower potential has been conducted firstly in Sichuan Province, one of the provinces with larger hydropower potential in China, and the study on economic developable hydropower potential has been listed in the plan. The evaluation principles of economic developable hydropower potential is that it must have competitive compared with other power sources, and the comprehensive analysis methods of the combination of macroscope and microscope, quantitative and qualitative analysis, and precision and fuzzyhave been taken. According to the quantitative calculation of national economic evaluation, the economic developable hydropower potential in Sichuan Province is 100. 4547 million kW and 540' 258 billion kW' h, accountingfor 31. 2% and 42' 6% of the country's total respectively.
