Aiming at water security issues existed in water resources development and utilization, studied the water resources carrying capacities of fifteen farms in Jiansanjiang branch bureau in 2008. Used grey correlation analysis to establish evaluation indices system. Entropy theory was introduced into weight calculation. Synthesized evaluation results of traditional matter-element model, fuzzy comprehensive evaluation model and fuzzy matter-element model to grade water resources carrying capacities. The results show that water resources carrying capacities of Farm Shengli, Qindeli, Qianshao and Qianfeng are gradeⅠ; carrying capacities of Farm 859, Daxing, Qinglongshan, Qianjin, Honghe, Yalvhe and Nongjiang are gradeⅡ; carrying capacities of Farm Qixing, Chuangye, Hongwei and Erdaohe are gradeⅢ.

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.

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.

With the growth of population, water security has become the worldwide problem combined with severe environment pollution, quick economic development and irrational water allocation. Based on sustainable development, Water resources carrying capacity (WRCC) driven from physics originally has been proposed to solve it. The measurement of WRCC can tell decision-makers that how much population the water resource can feed, what degree water resources can support the economic and so on. Because the decision-makers can make adaptive decisions based on the correct evaluation of WRCC, the ways of the assessment of WRCC are very important. This paper focuses on how to measure WRCC by selecting three typical methods, fuzzy model of comprehensive evaluation, multiple criteria analysis (MCA) and system dynamics (SD) methods. The characteristics of these methods are good at solving the multi-objective and complicated problem in common which is the trait of WRCC. The differences of them are the specific process of analysis and evaluation.

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

In the construction plan of the Xi'an-Xianyang Integration, water resources carrying capacity (WRBC) plays an important role in construction planning. Establish a comprehensive evaluation model of water resources carrying capacity in Xianyang City. 10 indexes of 5 categories, which were selected the analysis of relevant indexes including socio-economic indexes, water supply and demand indicators and water quality indicators, etc., were used to composing evaluation system. Using Cluster Analysis, Analytic Hierarchy Process (AHP) and Fuzzy Matrix. The sum of insecurity and less security coefficient of Xianyang City Water Resources Carrying Capacity is at about 0.7. The sum of more security and security coefficient is at about 0.3. And the safety coefficient of Water Resources Carrying Capacity in Xianyang City shows increasing trend. In Xi'an-Xianyang integration, through economic development, focusing on the construction of water and water pollution control, water resources carrying capacity is expected to increase in Xianyang City.

Abstract Jinan is a city that typifies the water resource shortage in North China. This study selected nine indices to evaluate the regional water resources carrying capacity (WRCC), which is an important constraining factor in relation to socioeconomic development and the ecological environment. The AHP-CRITIC weighting method was applied to determine the index weighting, and WRCC dynamics during 2011–2016 were analysed and evaluated quantitatively using the fuzzy comprehensive evaluation method. The results revealed the following. (1) During 2011–2016, the comprehensive score of the WRCC was <0.4, indicating poor WRCC. (2) The degree membership of the average evaluation results to V1, V2, and V3 increased successively during 2011–2016. The degree membership of V2 in 2011–2013 was greater than that of V3; however, the situation was reversed during 2014–2016. (3) The indices of available amount of water resources per capita, utilization rate of water resources, water supply per capita, modulus of water supply, quota of domestic water demand, and population density were factors that affected the WRCC of Jinan unfavourably. Conversely, the indices of water demand per 10,000 Yuan industrial output value and water use rate of the ecological environment were factors that played positive roles in improving the WRCC.

Abstract In order to solve regional water security issues, such as shortage of water resources, the aggravation of water pollution, the destruction of the ecological environment, etc., this study proposed the flood control security index, resource security index and ecological security index, respectively, according to the construction principle of human development index. Based on the above security indexes, a novel water security comprehensive evaluation model is established by combining the coupling coordination degree model and the state space model. The proposed model has the advantage of simple operation and fast data speed, which is convenient for water security evaluation in different periods and regions. Taking China as an example, the water security conditions were evaluated from 2007 to 2016 for 31 provincial-level administrative regions in China, including flood control security index, resource security index, ecological security index and water security level of each region, and the specific problems of water security in each region were obtained. The evaluation results are consistent with the actual situation in each region, which provides the scientific basis for the local government authorities to formulate the corresponding regional water security policy.
