摘要
辽宁省大连市和营口市是两座具有代表性的沿海城市,湿地类型较多且资源丰富。为了明确东北滨海湿地生态系统的现状,对大连市和营口市的湿地面积和生物多样性进行了调查统计。结果表明,大连市湿地面积为42524.94 hm^(2),营口市湿地面积为14957.07 hm^(2),沿海滩涂面积相对最大,分别为41695.54 hm^(2)和11694.78 hm^(2),灌丛沼泽面积相对最小,分别为5.62 hm^(2)和1.65 hm^(2);湿地植物和鱼类物种数较多,两栖类物种数最少,大连市湿地中植物有81科474种,营口市有30科134种,大连市湿地中鱼类有108科274种,营口市有58科124种,大连市湿地中两栖类有6科14种,营口市有4科5种。通过湿地生态系统概况、资源特点、保护现状、存在的问题等方面,阐述湿地对生态环境平衡的重要性,并提出湿地生态系统保护对策。
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 Northeas China,the wetland area and biodiversity in Yingkou and Dalian were investigated.The results showed that the wetland area of Dalian was 42524.94 hm^(2),while the wetland area of Yingkou was 14957.07 hm^(2).The coastal tidal flats accounted for the highest proportion,41695.54 hm^(2) for Dalian and 11694.78 hm^(2) for Yingkou respectively;while the shrub swamp accounted for the lowest proportion,5.62 hm^(2) for Dalian and 1.65 hm^(2) 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 124species 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.
