Grassland resources are an important part of land resources. Moreover, it has the functions of regulating the climate, windproof and sand fixation, conserving water sources, maintaining water and soil, raising livestock, providing food, purifying the air, and beautifying the environment in terrestrial ecosystems. Grassland resource evaluation is of great significance to the sustainable development of grassland resources. Therefore, this paper improves the BP neural network, uses the comprehensive index method to calculate the weights in the analytic hierarchy process, and constructs a water resources carrying capacity research and analysis system based on the entropy weight extension decision theory. Meanwhile, this paper analyzes different levels of resource and environmental carrying capacity to achieve the purpose of comprehensive evaluation of resource and environmental carrying capacity. In addition, based on the theory of sustainable development, under the guidance of the principle of index system construction, this paper studies the actual situation of grassland resources and the availability and operability of data, and combines with the opinions given by experts to form an evaluation index system of grassland resources and environmental carrying capacity. Finally, through the actual case study analysis, it is concluded that the model constructed in this paper has a certain effect.

Urban underground logistics system is a newly emerging concept, and there is no molded sample project to provide reference information. So there exists much uncertainty in its development, and such uncertainty will have some impact on overall development of the system. In this paper, gray analytic hierarchy process analysis will be used to evaluate the risk factors in the development of urban underground logistics system. And then, we use the empirical analysis to quantify the risk of the development of urban underground logistics and provide references for the development of urban underground logistics system.

China is a water resource-poor country, in recent years, rapid population growth resulting in water issues have become increasingly prominent. Taking Anhui Province as an example, using fuzzy synthetic evaluation method and combining the analytic hierarchy process evaluation analysis of water resources carrying capacity. Firstly, establishing the evaluation criteria of the index system of regional water resources carrying capacity and individual indicators, calculating evaluation index weight,establishing the weight fuzzy matrix, using Vague set and analytic hierarchy process method to determine the weight vector.Secondly, compositing a fuzzy matrix of weight values after obtaining the value of the weights of the various indicators, calculating the degree of membership, establishing the fuzzy relation matrix, fuzzy subset into a comprehensive evaluation model, and seeking the comprehensive evaluation value .Finally, determining the level of sustainable use of water resources in the specific area based on the principle of maximum degree of membership . After the evaluation are analyzed and compared in order to elaborate the evaluation method is feasible and effective.

Water Environmental Carrying Capacity

In this paper, the water environmental carrying capacity (WECC) was quantitatively analyzed considering the comprehensive effect of economy, society, resources, environment, and technology in Jiaozhou, Shandong province. An evaluation index system was established and applied in the evaluation of WECC in Jiaozhou from 2007 to 2011 with analytic hierarchy process (AHP) and vector modulus method. The results indicated that the WECC index was at low level in the range of 0.061-0.080 with the decreasing trend firstly but then increasing trend gradually, which shows that the water resources shortage is becoming the key factor restricting the development of Jiaozhou. The results conform to the real condition of Jiaozhou and the research provides the scientific methods and suggestions for the coordinated development of social economy and water environment protection.
