伊犁地区野生毛牛蒡和牛蒡的种群分布、生态和群落特性的研究

在充分踏察的基础上，选择具有代表性的样地，接线路调查法和样地调查法得出野生毛牛蒡和牛蒡种群的分布格局在伊犁地区总体上呈随机分布，占86．7％的调查样地；小范围内也有群聚分布的，占13．3％的调查样地；分布于喜光、低海拔、对土壤适应性高、生活力强等是牛蒡和毛牛蒡的生态习性；常与各类草本为伍，与菊科、禾本科、唇形科、藜科、蓼科、蒺藜科等常见科的植物均能共生于同一环境，是牛蒡和毛牛蒡的群落学特性；植被类型和人为因素是影响它们分布的环境因素。

Study on the Distribution and the Ecology Characteristic of the Wild Arctium in Yili Area

Chose representative samples and researched the pattern of distribution of the wild Arctiurn in Yili area, it was stochastic in the mass （86.7% samples） and distributed at ditches, field brims or tussocks. But there was multitudinous at occasional cause （13.3% samples） and distributed at meadow, sparse hurst or at the border of the forest. Discussed the ecology characteristic, the community characteristic and impact environment factors. Tabled a proposal to protect the wild Arctium resources.
