Study On Evaluation Of Cultivated Land Ecological Security Of Jiangsu Province Based On Entropy Fuzzy Matter Element Model

Cultivated land ecological security was a significant foundation for the land resources sustainable development and the ecological civilization construction. To solve the problems of information asymmetry and subjectivity existing in most integrated evaluation studies, an evaluation index system based on the Driving-Pressure-State-Impact-Response (DPSIR) model was constructed, and then an evaluation model of the cultivated land resources ecological security was established based on fuzzy matter-element in which the modified entropy objective theory was used to determine the index weight. The model was adopted to carry out a case study on Jiangsu Province. The calculated comprehensive scores of ecological security showed that the level of cultivated land ecological security of Jiangsu Province was on the rise and the ecosystem service was comparatively functional because the land resources were being protected much better.
