山东省南四湖湿地植被及其生物量初步研究

Preliminary Study on Wetland Vegetation and Its Biomass of NanSihu Lake in Shandong Province

摘要:

通过对南四湖湿地野外实地调查并结合已有资料，对南四湖湿地范围进行了重新界定，分析了湿地的植被状况。并对2006年6月的SPOT5影像进行解译，绘制了湿地景观格局图并统计各种景观类型的面积。使用湿地植被生物量密度数据计算出整个南四湖湿地植被的生物量为623.37×103t，并与1983年资料对比发现南四湖湿地植被生物量已减少了4/5，表明南四湖湿地植被的初级生产能力已经明显减退。

Abstract:

Based on the fieldworks in Nansihu lake and some existing datas, the range of Nansihu lake was redefined and conditions of wetland vegetation was analyzed in the paper. After the interpretation of the SPOT5 datas in 2006, the wetland landscape pattern figures have been made and the areas of different kinds of landscape patterns have been calculated. By using the published datas of wetland vegetation biomass density, the biomass of Nansihu lake wetland vegetation is 623.37×103t, which has been decreased by 4/5 compared with the information in 1983. The results indicated that the primary production of Nansihu Lake wetland vegetation has reduced obviously.
