黄脊竹蝗空间格局及抽样技术的初步研究

Studies on The Spatial Distribution Pattern and Sampling Technique of Ceracris Kiangsu Tsai

本文采用聚集度指标法和回归分析法 ,对黄脊竹蝗在林间的空间格局进行测定 ,并采用刀切法给出了聚集度指标的估计区间 ,3次设计最优拟合提高了回归模型参数的精度 ;结果表明 ,黄脊竹蝗在林间为聚集分布 。

Measured by clump intensity index and regressive analysis method, the spatial distribution pattern of nympha of Ceracris kiangsu Tsai is confirmed to aggregation distribution with Jackknife estimation, the range of clump intensity index was provided. The parameter precision of regressive model was improved by the optimal fitting of three designs.
