Water Resources Carrying Capacity

The water resources carrying capacity is an important component of natural resource carrying capacity in a country or region sustained development process. It is the key being related to using the water resources reasonably, which means vital to the sustained growth of the water resources, the social economy and the ecological environment concordant development.Taking the case of river basin in arid zone of the Manasi River Basin,The author evaluated water resources supporting capacity condition basin in different year of the Manasi River by establishing fuzzy comprehensive evaluation model. The results indicated that because of saving water technological progress and industry restructure advancement, the water resources carrying capacity of Manasi River will be improved in the future twenty years. The water resources supply and demand contradictory will be obtained certain alleviation, but the uneven of water resources space and time distribution is still the main restrictive factor of the development of society and economic and the ecological environment construction.

Abstract As one of the most serious water-shortage regions of China, the shortage of water resources and ecological deuteration of the Tarim River Basin has increasingly attracted attention, and management and sustainable utilization of water resources rely mostly on the understanding of their carrying capacity. In the present study, water resources carrying capacity of the Tarim River Basin was evaluated using a multi-dimensional perspective of nature, society and economy factors based on a variable fuzzy evaluation model for the 2018 hydroclimatic conditions. Evaluation model results rated Aksu, Kizilsu, Kashi and Hotan districts as grade 2, where water resources current use and overexploitation have reached a relatively high level combined with a limited water resources carrying capacity. Bazhou district, where the water resources carrying capacity is relatively higher was evaluated and rated as grade 1 by the model. It is urgent to put forward some strategies in order to protect and improve the water resources carrying capacity in the Tarim River Basin which include promoting more efficient utilization of water conservation schemes, strengthening the long-term investment in environmental protection, improving the ratio of industrial wastewater treatment and reducing the industrial water quota. The results of the present study are aimed to be a beneficial guide in the planning and management of the Tarim's River basin water resources and possibly for other similar river basins.

Water resources carrying capacity is the maximum available water resources supporting by the social and economic development. Based on investigating and statisticing on the current situation of water resources in Shandong Province, this paper selects 13 factors including per capita water resources, water resources utilization, water supply modulus, rainfall, per capita GDP, population density, per capita water consumption, water consumption per million yuan, The water consumption of industrial output value, the agricultural output value of farmland, the irrigation rate of cultivated land, the water consumption rate of ecological environment and the forest coverage rate were used as the evaluation factors. Then,the fuzzy comprehensive evaluation model was used to analyze the water resources carrying capacity Force status evaluation. The results showed : The comprehensive evaluation results of water resources in Shandong Province were lower than 0.6 in 2001-2009 and higher than 0.6 in 2010-2015, which indicating that the water resources carrying capacity of Shandong Province has been improved.; In addition, most of the years a value of less than 0.6, individual years below 0.4, the interannual changes are relatively large, from that we can see the level of water resources is generally weak, the greater the interannual changes in Shandong Province.

Manas River Basin

Because lack of water resources in Manas river basin, the water resources carrying capacity evaluation is important to the water sustainable development. In this paper, we select the main factors of the water resources carrying capacity and separate into water resources subsystem, social subsystem, economic subsystem and ecological subsystem. Then established three evaluation models to evaluate the different years of water resources carrying capacity and made the application comparison. The fuzzy comprehensive evaluation model and matter-element models are adaptable to the water carrying capacity evaluation, but the determination of weights is too subjective; The projection pursuit theory is based on the sample characteristics of their own, and without given weight of each indicator, the results is more objective. The results show that the water resources carrying capacity in Manas River basin was at V1-stage in 2000; it is at V2- stage in 2010 and V3- stage in 2020, and then the water resources carrying capacity in Manas River basin is the ideal carrying capacity status. At the same time, because of saving water technological and industry restructure adjustment, water resources carrying capacity in Manas River Basin is on a benign trend. At last, some measures of improving the water resource carrying capacity were put forward.

Based on adequate consideration of status of water resources utilization and socio-economic development in the Shanxi Provinces, the AHP method was used to calculate the weights of each index and the fuzzy comprehensive evaluation of water resource carrying capacity in the Shanxi Province was carried out from 2006 to 2011. The evaluation results indicated that the overall level of the water resources carrying capacity in Shanxi Province was contained in critical state, however, a steady rise.

The carrying capacity of water resources is one of the focuses in water resources research, and it has an important significance in measuring the effects of water resources on regional development. Wuhan City is selected as an example in this study. Eight indexes are selected to assess the carrying capacity of water resources in Wuhan City in recent three years based on the fuzzy comprehensive evaluation method. The results show that the degree of exploitation and utilization of water resources is relative high, and the potential of carrying capacity is relatively small. In addition, the contradiction between supply and demand of water resources is outstanding, and it tends to overload. The fundamental measures are put forward to improve water resources carrying capacity such as improving the utilization efficiency of water resources and enhancing the capacity of water saving from the perspective of promoting economic and social development
