目的 研究毛红椿天然群体遗传多样性取样策略，为其种质资源收集、保存和遗传多样性保护等提供参考依据。 方法 利用8对微卫星分子标记进行毛红椿天然群体遗传多样性和空间自相关分析，综合制定其天然群体合理取样策略。 结果 毛红椿天然群体等位基因数平均为7.5个，期望杂合度（H_e）和多态性信息指数（PIC）均值分别为0.6437和0.6360，基因分化系数（G_ST）均值为0.2907。在遗传多样性取样策略方面，提出了根据毛红椿群体基因分化系数来确定取样群体遗传变异所占总变异比例的运算公式为1-（G_ST）^n-1，其中，n为取样群体的数量。当取样群体达到4个时，基本上能包括该树种97. 5%的遗传变异；同时确定了目标群体的选择方法，应选择与其它群体间基因分化系数均值较大的4个群体，即贵州册亨（CH）、浙江遂昌（SC）、浙江仙居（XJ）和云南师宗（SZ）。通过构建云南宾川（BC）、云南师宗（SZ）和江西宜丰（YF）群体内取样单株数量与基因多样性和等位基因之间的捕获曲线，确定了群体内取样单株数量应达到15个以上；毛红椿天然群体内300~520 m范围内的单株间存在相似关系，超出此范围个体间差别较大，说明在进行群体内单株取样时，单株间距应大于520 m。 结论 取样群体数量、群体间遗传分化系数、群体内单株数量以及单株间距离等影响了毛红椿取样群体的遗传多样性。毛红椿天然群体遗传多样性取样策略为取样群体4个、每个群体最少取样15个单株，单株间距大于520 m

The partial correlation analysis on the relationship between the main meteorological factors and daily emergence amount of Carpomyia vesuviana overwinter generation adult from the beginning to the peak of emergence was conducted. The results of stepwise regression analysis show that the air temperature, the soil temperature and the relative humidity of soil are the main meteorological factors affecting the emergence amount of overwintering emergence. The results of Path analysis and decision-making system analysis show that the air temperature has positive affect on the emergence and is an important index directly impacting on the emergence amount of C. vesuviana; The soil temperature is the most important factor limiting the amount of emergence; the soil relative humidity has the greatest comprehensive influence on the amount of emergence. Based on partial correlation analysis, a multiple regression equation was established on the main meteorological factors and C. vesuviana overwintering generation adult emergence. The emergence amount predicted by the model is significantly correlated with the amount of emergence which was field measured. So this model is applicable for forecasting the amount of C. vesuviana overwintering generation adult.
