State Response

The ecological system and natural environment of islet in river are easy to be damaged. With the increasing tourists and serious lag of management, the ecological environment of islet in river is facing severe challenges and its ecological environmental security should been paid more attention. Based on the model of Press-State-Response, the article constructed the evaluation index system of islet in river and applied it in the evaluation of Dongzhou islet of Hengyang, Hunan province of China. The research can provide the reference for ecological security evaluation and environment protection. It will promote the islets tourism utilization and sustainable development.

Fuzzy Pattern

Through identifying the exploitation and utilization of water resources system, this paper establishes an improved fuzzy pattern recognition model by combining fuzzy matter-element model with the improved entropy evaluation method and sets up the comprehensive evaluation index system which includes 3 layers and 10 indicators from two aspects: water utilization efficiency and water ecological environment. The proposed model and evaluation index system are applied to evaluate the comprehensive exploitation-utilization grade in Shandong Province. Results show that the exploitation-utilization of water resources and water ecological environment are not balanced in Shandong province, this indicates that the growth of ecological benefits and the protection of water ecological environment are ignored in the process of water resources exploitation-utilization.

The Impact

Water resources is an important basic energy. The determination of weights is one of the important indexes in water resources evaluation system and reasonable allocation of weights is the key to quantitative evaluation. In order to establish a scientific evaluation index system of the influence of mining disturbance on water resources for purpose of a more reliable and effective evaluation result and realizing the protection of water resources system, a comprehensive evaluation system of water resources based on PSO-AHP model is proposed in the paper. Combined with the specific geological environment characteristics of mines, this paper establishes a four-level evaluation index system after identifying the factors affecting water resources and ecological environment. By applying the particle swarm optimization (PSO) to the analytic hierarchy process (AHP) and fuzzy comprehensive evaluation method, a PSO-AHP model and then a fitness function are constructed to solve and optimize the weight values in the evaluation index system, and the calculated weight values are checked by consistency checking method. The evaluation results suggest that the index system can accurately reflect the impact of mining on water resources and water ecological environment and etc., providing certain reference value for sewage resourcing and reducing the harmful effect on environment by sewage discharge.

Guangzhou is the capital city of Guangdong Province, which is currently in a stage of transformation and development. This paper takes Guangzhou’s ecological economy, ecological society, ecological environment as the research objects and constructs an evaluation index system for Guangzhou’s ecological liveability. It takes social progress, economic development and environmental protection as the primary indicators. The index system is used to construct the ecological livability evaluation index system of Guangzhou through the entropy method.

General Applicability

Based on the model of ecological environment evolution in the process of the economic development, this paper constructed the evaluation index system of marine ecological environment. The results were shown as follows: the evaluation index system of marine ecological environment consists of 1 object layer, 3 element layers (state of marine ecological environment pressure of marine ecological environment and response of marine ecological environment), and 15 factor layers. Index weight was calculated through combination weighting approach of subjective and objective evaluation method of analytic hierarchy process(AHP) and entropy method. The evaluation indicator system and evaluation method have general applicability and strong operability.

The Index System

Effectiveness evaluations are one of the important ways to guide grid investment and to improve investment efficiency. Improving the effectiveness of grid investment evaluations is studied based on the optimization of the investment evaluation index system and the utility evaluation model. The index system is optimized by establishing an evaluation index system of grid investment effectiveness, considering the redundancy between the indices, and constructing an ISM-DEA model. The utility function model was introduced to fully consider the different risk appetites of decision-makers, and a utility evaluation model that takes risk appetite into account was established. An improved weight integration model based on multiobjective optimization was established by considering the minimum deviation and the trend-optimal objective function when setting the index weights. The calculation results show that the feasibility of the index system optimization model and utility evaluation model constructed in this study is verified under the premise of satisfying the assumptions. By adjusting the risk preference coefficient of decision-makers, the dynamic optimization of the grid investment utility evaluation results can be realized.
