Abstract


This paper is in the country \water balance , to carry out wetland ecosystems hydrological connectivity study . This paper summarizes abroad on hydrological connectivity research progress made ??hydrological connectivity concept , the main contents and methods , combined with wetland hydrological structure proposed wetland ecosystems hydrological connectivity calculation method and hydrological connectivity eigenvalues ??indicators , combined with water wetlands , and to explore the wetland hydrological connectivity and storage capacity of the correlation. In the Songhua River Wuyu'er - Shuangyang River Basin Zhalong wetland as an example, select Zhalong wetland landscape at different phases of the five remote sensing images, through interpretation of remote sensing and ArcGIS spatial analysis tools analyze Zhalong wetland surface area and distribution of changes , combined with the different years of annual runoff , precipitation and evaporation data , analysis Zhalong wetland water storage changes driven by changes in the hydrological connectivity proposed wetland hydrological connectivity is calculated. Wetland water conditions is to determine the key factor in the survival of wetlands , wetland hydrological connectivity to reflect changes in wetland hydrology and ecological relationship between structure and function , is a reflection of the health of wetlands is an important indicator . The research results can water resources planning and management of wetlands provide a scientific basis for wetland protection and restoration of ecosystems to provide technical support.
