武汉藏龙岛湿地公园山体植被景观分析及改造建议

Suggestions for Landscape Analysis and Transformation of Mountain Vegetation in Wuhan Canglong Island National Wetland Park

藏龙岛国家湿地公园是武汉市江夏区重要的城市绿地之一,在汤逊湖东部起到了生态保护、居民游憩、自然教育等重要功能作用。针对湿地公园内多个不同区域山体的半自然林地进行了调查,并分析了其景观效果、空间功能和群落情况,用林相改造理论和顶级群落理论作为基础,分析了相应生境下的改造建议和种植设计。提出了以下建议:加强竹林景观区的人工养护工作、郁闭度高但物种单一的区域疏伐少量外来树种和先锋树种制造林窗以促进群落演替、补植部分本土树种增加丰富度、临近游憩区和步道边沿的地区适当培育低养护的自生植被景观、只有上层乔木+地被植物的地区适当补充中层植被等。

Canglong island national wetland park is one of the important urban green spaces in Jiangxia District,Wuhan.It plays an important role in ecological protection,residents'recreation and nature education in the eastern part of Tangxun Lake.This study investigates the semi-natural woodland of mountains in many different regions in the wetland park and analyzes its landscape effect,spatial functions and community situation.Based on the forest phase transformation theory and the top community theory,it analyzes and provides transformation suggestions and planting design under the corresponding habitat.The recommendations are as follows.Artificial conservation should be strengthened in bamboo forest landscape areas;a few exotic and pioneer tree species should be thinning in areas with high canopy density but single species to create forest windows to promote community succession;some native tree species should be supplemented to increase richness;low-conserved spontaneous vegetation landscape should be cultivated in areas close to recreation areas and trail edges,and middle-level vegetation should be supplemented in areas with only upper layer trees and ground cover.
