Evaluation of Water Resources Ecological Service Function based on Agricultural Food Perspective

摘要

Water resource is the material basis of human survival that closely linked with human living and production activities and is one of the most important factor restricting the natural environment, human survival and development. In this study, we aim to explore water ecosystem service function by set up the evaluation index system, which is based on the principle of evaluation index selection and combining with the existing research involved in water ecosystem evaluation index. By using questionnaire to collect data, we make empirical analysis based on factor analysis method. According to the model as each evaluation factor scores and overall value, we analyze water resources ecological service function and find out the factors that will influence ecological function. Finally, we find out the advantages and disadvantages according to the result of model evaluation and then put forward relevant policy suggestions.
