贵阳市水资源承载状态时空特征研究

水资源承载力的研究源于日益突出的缺水危机,基于文献对水资源承载力及其承载对象的研究,认为人类经济活动的季节性是影响水资源承载状态的主要因素之一。参考月蓄水量动态变化确定研究区的水资源供给量的季节变化规律。利用不同特征经济区的经济增长率和人们生产活动的季节性模数确定水资源承载对象的季节性变化规律,探讨水资源承载状态时空变化的量化方法,建立了基于水资源供给与经济活动规模互动的水资源承载状态评价模型。研究认为云岩、南明两城区水资源承载状态的季节变化较大,在枯水季节容易发生水资源超载而引发的水危机;而修文、息烽等县水资源承载状态的季节性变化较小,在枯水季节的超载程度较轻。研究将为区域可持续能力建设提供有益的参考。

A research on spatio-temporal characteristics of the water resource carrying status in Guiyang City

Challenged by the water shortage, the carrying capacity of the water resource was fully researched. According to the analysis of water resource carrying capacity and its carrying objects, the seasonal varieties of the residenter economic activities were main influencing factors. According to the changing characteristic of the moon sluice in the area of Guiyang, the seasonal variability was taken into accounted in the water resource carrying capacity researches. Based on the seasonal changing law that was ascertained by the seasonal economic activity index and the economic increasing rate in the area of Guiyang city, the quantitative assessment was developed by means of the study on the reaction of water carrying capacity and its carrying objects. In view of the study, there were large seasonal varying value of water resource carrying capacity and high probability of water scarce conjunctures during the low water season in the urban districts of Nanming and Yunyan, while there were smaU seasonal varying value of water resource carrying capacity and low probability of water scarce conjunctures during the low water season in the counties of Xifeng and Xiuwen. The status data of the water resource carrying capacity can provide a reference for the future study on the sustainable ability construction.
