Ecosystem Change and Its Impact Factors in Yellow River Delta

This paper exhibited the change process of the delta wetland and then discussed the factors that related to wetland degradation. Based on the implementation of wetland restoration, effects on wetland process were analyzed. Results showed that before restoration, wetland landscape tended to fragmentation and biodiversity decreased, while after restoration, wetland ecosystem was objected to develop favorably. By correlation analysis, factors related to wetland degradation were mainly groundwater depth and salt content.
