| Abstract: | In the study, we analyze and assess quantitatively the spatial pattern of vegetation and its ecological degradation information
in the Honghe National Nature Reserve (HNNR), a Ramsar-designated site in Northeast China. Statistics from historical survey
data are used to measure the degradation of marshes over time and changes in the hydrological regime. Long-term statistical
data are also employed to analyze both natural and human impacts on these changes. Both the wetland degradation model and
its mechanisms are discussed in this paper. The research finds that the loss of water and other types of degradation in the
vegetation habitat caused by the rapid deterioration of the hydrological regime has threatened the status of HNNR as a “storage
area of natural genes.” Scientifically constructed strategies are urgently required to ensure sustainable economic benefits
that do not adversely affect this nature reserve. |
