| 摘 要： | 喀斯特地区水文运动规律特殊,生态环境脆弱,其水资源承载力也不同于非喀斯特地区。本文从喀斯特地区的水资源承载力入手,选取了供水模数、需水模数、水资源开发利用程度、人均供水量、工业用水重复利用率、耕地灌溉率、生态环境用水率等评价指标,并用多目标灰色关联投影法对贵州省各地区的水资源承载力状态进行了合理排序。最后对人口、GDP、水资源量和喀斯特面积与评价结果进行了灰色关联度分析,得出以上四因素与喀斯特地区的水资源承载力具有一定的关系,其关联程度大小顺序为:水资源量>人口>GDP>喀斯特分布面积;喀斯特分布面积对其水资源承载力具有一定程度的影响,喀斯特地区经济发展的落后导致其经济发展与水资源承载力关系不明显;随着经济技术水平的提高,喀斯特分布面积对水资源承载力的影响将逐渐减小。

| Abstract: | The hydrologic motion law of karst area is special,the karst ecological environment is frail and the water resource carrying capacity is different from non-karst area.Based on the water resource carrying capacity in karst area,the authors select the following assessment index systems:water supply modulus,water requirement modulus,water resources exploitation and utilization rate,average water resources amount per capita,industry water resources utilization rate,infield irrigation rate and environment water resources utilization rate,and then make an reasonable arrangement to the state of water resource carrying capacity in Guizhou province.It showed that the water resource carrying capacity in Qiannan state is the highest,while it is the least in Guiyang.Finally,the gray correlation coefficients analysis between the assessment results and the factors(population,GDP,water resource amount and the area of karst distribution) is made.And the analysis proves that there is some correlation between the factors and water resource carrying capacity.The order of the correlation coefficients is as follows: water resources amount > population > GDP > karst area.The area of karst distribution is of certain effects to water resource carrying capacity.Economic level almost has nothing to do with water resource carrying capacity for the backwardness of economic development in karst area.With the development of economy and technique,the influence on water resource carrying capacity by the area of karst distribution will reduce gradually. |
