摘要
为掌握云南薇甘菊危害核心区内薇甘菊发生危害的分布特征,2010年11月22日沿滇缅公路木康至畹町桥段路肩两侧200 m进行薇甘菊发生危害情况调查。结果表明,滇缅公路薇甘菊分布不连续,呈板块、点状分布;纬度越低,距中缅边境越近,薇甘菊发生、分布点频度越高;薇甘菊发生点盖度变化大,厚薄不均,发生面积大小不等;危害植物高度由被侵害植物高度决定;覆盖能力强,危害植物种类多,表现极强的入侵、侵害性;薇甘菊分布点多在农业耕作区的田边、地角以及稀疏林地、河流、溪水、水沟边和农户院落四旁;林木郁闭度大的林地薇甘菊危害相对较轻,完全郁闭的林中尚未发生薇甘菊危害。
In order to master the distribution characteristics of Mikania micrantha jeopardize status in core area, the occurrence and damage status of Mikania micrantha have been surveyed on both sides of 200 m along Burma road from Mukang to Wanding. The results showed that the distribution of Mikania micrantha was scattered, the distribution frequency was high in lower latitudes, or near the China-Burma bored; occurrence coverage of Mikania mierantha was changeable with uneven thickness and area, Mikania micrantha showed strong invasive ability on various plant species; and its distribution point focused in farmland, sparse woodland, rivers, streams, ditches and farmers courtyard; the hazard status of Mikania mierantha was relatively light in high canopy density forest, but has not yet occurred in fully canopy forest.
