简介：以便理解在落叶松种植园在微地点条件和自然新生上变瘦的效果，变瘦的实验在东方辽宁省在Qingyuan县在40-year-oldLarixolgensis种植园被进行，在2003-20的中国(14。Fivethinning处理(0%，10.2%，19.8%，29.7%和40.3%变瘦)在一样的地点上被设计。在变瘦以后，象光合的光子流动密度(PPFD)那样的华盖坦诚和微地点条件，土壤含水量，和土壤温度在一生长期被测量。同时，自然新生的调查在生长期的结束被进行。结果证明华盖坦诚随变瘦的intensities.PPFD和土壤温度的增加增加了，在不同土壤层的土壤含水量与在变瘦以后的华盖坦诚是确实相对的。改革树种类的丰富显著地没增加(p=0.30)自从变瘦，而是新生，在一生长期以后，树种类的密度和频率显著地增加了(p<0.05)。另外，改革树种类的数字增加了，并且增长与单个树种类的特征被相关。改革shade-intoleranttree种类的幼苗的增加的百分比多于阴影容忍的树种类的。在调查新生种类之中，到华盖坦诚的幼苗紧急情况的最大的反应是Phellodendronamurense。这篇论文证实了下列结论：在变瘦以后，改革树种类的变化是有在调查落叶松种植园改革unthinned树和地点条件的树种类，和分发的特征的关联词是影响新生的另外的因素。
