| Swine industry is not only the key project of the basket project,but also an important way to increase farmers' income.With the accelerated pace of China's ecological civilization construction,the relevant departments to increase the control of swine industry,resulting in the current decline in the number of swine,pork prices rose significantly.At present,the evaluation of the ecological level of swine farms are still in its facilities and systems.Compared with the current development of ecological theory,this evaluation method highlights its unilateralism.Therefore,this paper intends to use DPSIR conceptual model to build a more systematic evaluation method of ecological level of swine farms.Firstly,this paper reviews the relevant literature and theory,and defines the concept and content of ecological evaluation of swine farm.The ecological factors of swine farm were analyzed by using DPSIR model.On the basis of this,the evaluation system is constructed,which is composed of driving force,pressure,state,influence and response.The use of indexes obtained after construction of DPSIR model based on the index of pay more attention to the driving force and the influence of the AHP based on consulting relevant experts on the evaluation methods for evaluation of swine farm ecology provides a more systematic and comprehensive.This paper uses the fuzzy comprehensive evaluation method to evaluate the sample swine farm,and the evaluation results are good.Finally,this paper summarizes the characteristics of the index system of DPSIR model is obtained on the swine farm ecological regulation revelation,that regulation needs overall consideration from the angle of the system,not only to regulate the facilities and systems,more important is the impact on the overall regulatory environment of the swine farm.At the same time,the article holds that the standard of supervision should keep the dynamic and keep the linkage between the development of science and technology and the consumption demand. |
