Resources Planning

As one of the most crucial indices of sustainable development and water security, water resources carrying capacity (WRCC) has been a pivotal and hot-button issue in water resources planning and management. Quantifying WRCC can provide useful references on optimizing water resources allocation and guiding sustainable development. In this study, the WRCCs in both current and future periods were systematically quantified using set pair analysis (SPA), which was formulated to represent carrying grade and explore carrying mechanism. The Soil and Water Assessment Tool (SWAT) model, along with water resources development and utilization model, was employed to project future water resources scenarios. The proposed framework was tested on a case study of China’s Han River basin. A comprehensive evaluation index system across water resources, social economy, and ecological environment was established to assess the WRCC. During the current period, the WRCC first decreased and then increased, and the water resources subsystem performed best, while the eco-environment subsystem achieved inferior WRCC. The SWAT model projected that the amount of the total water resources will reach about 56.9 billion m3 in 2035s, and the water resources development and utilization model projected a rise of water consumption. The declining WRCC implies that the water resources are unable to support or satisfy the demand of ecological and socioeconomic development in 2035s. The study furnishes abundant and valuable information for guiding water resources planning, and the core idea of this model can be extended for the assessment, prediction, and regulation of other systems.

Water resources carrying capacity was evaluated by using fuzzy comprehensive evaluation method after the evaluation index system was constructed according to water resources condition, socio-economic development level and economic structure characteristics in Heifei City. The results showed that development and utilization degree of water resources was high and further development and utilization potential was small. The water resources development potential of city proper was the minimum in all regions and WRCC of it was saturated. The development and utilization degree of water resources in Feixi County was smaller than other districts, there were certain development potential. On this basis, some suggestions and measures were proposed for improve regional water resources carrying capacity and ensure regional sustainable development.

Water resources carrying capacity (WRCC) is an important factor which influences development speed and scale of society and economy. The evaluation index system of WRCC was constructed according to municipal economic development status and the utilization of water resources in Suzhou City, using the fuzzy comprehensive evaluation method, analyzed water resources carrying capacity in different years. The results showed that water resources carrying capacity has tended to be smaller in recent years. It indicated that the development and utilization of water resources were large, water resources carrying capacity was close to saturation and the development potential of water resources was small in Suzhou City.

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.

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.

Pair Analysis

In view of the uncertainty of evaluation indicators for water resources carrying capacity the theory of set pair analysis is adopted. The samples are preliminarily classified by calculating the connection degree between the samples and evaluation indicators. Then the samples are further ranked through the identity, difference and antagonism set pair analysis. The weights of evaluation factors in the model are obtained from the avail value of data reflecting the information entropy, by which the weight allocation is more reasonable. The application result of this model to an example is compared with those obtained from integrated evaluating methods and the attribute recognition method. It shows that the proposed method is practical and reasonable.
