洞庭湖区林网、洲滩湿地考察及利用之管见

Application and investigation for the forest and wetland of the Dongting Lake area

为探讨洞庭湖区湿地保护利用技术问题,我们对其进行了调查,并结合以往研究成果,分析研究并提出了:(1)农田林网、防浪护堤林,杨树生产和湿地保护已经产生了很好的效果;(2)农田林网、防浪林骨干林带还在,但结构受损,杨树有从林用地向农田和湿地自然保护区扩张之势,杨树品种混乱,湿地的核心保护区已受到诸多的人为干扰;(3)杨树在洞庭湖区发展的最大面积为11.94ⅹ104～12.33ⅹ104hm2,但应科学规划与合理布局,规范栽培品种,适地适树,开沟排水,畅通水流,加强抚育管理,培育无节良材,控制病虫害;(4)修复农田林网和防浪林结构;(5)建议湖区4个湿地自然保护区"四区合一",实行省、县两级管理。

Based on the investigation of the research results showed that protecting the wetland in the Dongting Lake area resulted in:(1)the farmland, forest, wavebreak forest, poplar plantation and protection of wetland had good effects;(2) few key forests were damaged in the poplar growth on to farmland and in the wetland nature protection zone,the poplar variety results were nonconclusive, the key protection zone of wetland were damaged by people;(3)the poplar forest in the Dongting Lake area was the biggest forest measuring 11.94×104～12.33×104?hm2.Managers should pay attention to the scientific program and design,standardize the variety of poplar use,strengthen the management of the plantation,breed improved varieties and control plant diseases and insect pests;(4)restore the structure of farmland,forest and wavebreak forests;(5)and the four wetland nature protection zones should unite and be managed by province and county government.
