Present Situation of Wetland Resources and Protection Countermeasure in Dalian and Yingkou
Dalian and Yingkou are two representative coastal cities in Liaoning,which have many types of wetlands and rich resources.In order to clarify the current situation of typical wetland ecosystems in Northeast China,the wetland area and biodiversity in Yingkou and Dalian were investigated.The results showed that the wetland area of Dalian was 42 524.94 hm2,while the wetland area of Yingkou was 14 957.07 hm2.The coastal tidal flats accounted for the highest proportion,41 695.54 hm2 for Dalian and 11 694.78 hm2 for Yingkou,respectively;while the shrub swamp accounted for the lowest proportion,5.62 hm2 for Dalian and 1.65 hm2 for Yingkou,respectively.As for the wetland biodiversity,it was found that the proportion of wetland vegetation and fish was the highest,while the proportion of amphibians was the lowest.Among them,Dalian had 81 families of 474 species of wetland vegetation,while Yingkou had 30 families of 134 species of wetland vegetation;Dalian had 108 families of 274 species of fish,while Yingkou had 58 families of 124 species of fish;Dalian had 6 families of 14 species of amphibians,while Yingkou had 4 families of 5 species of amphibians.This paper expounds the importance of wetland to the balance of ecological environment and puts forward the protection countermeasures of wetland ecosystem through the general situation,resource characteristics,protection status and existing problems.
