辽宁北镇新立湖国家湿地公园湖塘堤坝植物群落调查研究

Investigation and Study on Plant Communities in the Dike of Xinli Lake National Wetland Park in Beizhen, Liaoning Province

为了解新立湖湿地公园植物的自然本底,更好地保护生态环境,充分发挥其生态效应,采用121个样方重复调查的方法,对新立湖湖塘堤坝的植物群落进行调查研究。结果表明:新立湖湿地公园有植物51科182种,其中优势种植物6种,分别为香蒲、芦苇、水蒿、葎草、地肤和藜,第一大优势植物为香蒲,第二为芦苇;调查区内的优势种植物与伴生种植物的关系为相互抑制、相互促进、对立统一。最后提出了大力推进稻田养蟹的生产模式、减少除草剂的使用及清除三裂叶豚草的保护建议。

In order to understand the natural background of plants in Xinli Lake Wetland Park,better protect the ecological environment and give full play to its ecological effects,the plant communities in the ponds and dams of Xinli Lake were investigated by means of repeated investigation of 121 plots.The results showed that there were 182 species of plants in 51 families in Xinli Lake Wetland Park,among which 6 dominant species were Typha orientalis,Phragmites communis,Artemisia selengensis,Humulus scandens,Kochia scoparia and Chenopodium album.The first dominant plant was Typha orientalis and the second was Phragmites communis.The results of investigation and observation also showed that the relationship between the dominant species and the associated species in the survey area was:mutual inhibition,mutual promotion,unity of opposites.Some suggestions for the protection of plant diversity were put forward,such as vigorously promoting the production mode of crab culture in rice field,reducing the use of herbicides,and eliminating ragweed.
