The effects of meterological factors on the growth quantity of Larix leptolepis were different analyzed by step-by-step regression and correlation coefficient analysis.

采用多元逐步回归方法和关联分析法得出的气候因素对日本落叶松生长量影响的排序次序是有差异的，但基本结论具有共同性：影响重要的气象因子不管是上年夏季的降水量，还是上年9～10月相对湿度都与降水有关，表明该地区日本落叶松生长量与降水状况和春季地温有密切关系。

The results indicated that a molecular identification system for the physiological races of Melampsora larici-populina in China could be established through cosmically searching special RAPD fragments of different races.

此结果表明，通过寻找落叶松杨栅锈菌生理小种的特异性RAPD片段，能够建立起中国落叶松杨栅锈菌生理小种的分子检测体系。

Analyzing the DNA Polymorphism: 14 random primers were selected to analyze the DNA polymorphism of 13 species of Melampsora larici-populina, the result indicates: The isolates of MLP have resemblance and difference, thee differences reflect the DNA Polymorphism of them.But the Polymorphism is not related to their origin.the result is consistent with departed one.

2DNA多态性分析：用所选出的14条随机引物对13种落叶松-杨栅锈菌进行RAPD分析，发现落叶松—杨栅锈菌菌种之间既有一定相似性，又具有明显的遗传多态性且多态性与地理来源没有必然的相关性，这与以往的结论相一致。

This article assures that silviculture of Tilia amurensis and Larix olgensis mixed forest is successful, by the means of studying on the growth of these two tree species and their interspeeific relationship.

本文通过对椴树(Tilia amurensis Rupr。)落叶松混交林生长和种间关系研究，肯定了营造椴、落混交林是成功的，合理混交能促进椴树和落叶松生长。

The drying characteristics of small-diameter lumbers of Larch and Cathay poplar, located in the Northeast of China, were investigated.

本文以东北地区常见的落叶松和大青杨小径木为研究对象，较为全面系统地研究了小径木落叶松和大青杨锯材的干燥特性。

Logistic regression was used to model tree mortality of Larix based on the data from l31 diameter-class groups of l2 forest management inventory remeasured plots in Wangqing Forestry Bureau of Jilin Province.

根据来自吉林省汪清林业局森林经理调查的12个落叶松复位样地的131个径阶组数据，应用Logistic型回归式建立了落叶松林木枯损模型。

High-quality production northeast traditional red, white, larch wood again welcomed by a number of sales areas, processed white pine, larch, Pinus sylvestris better sales of the plate.

高品质的生产东北传统的红，白，落叶松木材再次欢迎一些地区的销售，加工白松，落叶松，樟子松更好地销售板块。

This paper comparatively studies evapo-transporation of 6 representative forest types,such as young growth larch,half-mature larch ,young growth Korean pine,half-mature Korean pine,oak,weed tree,in mountain- ous area of eastern Liaoning by observing fixed plots.

本试验运用固定标准地观测的方法测定辽东山区几种主要林分类型的蒸发散量，根据布兰尼—尼里德尔模型推算的后楼水库集水区邻域范围内的年土壤和枯落物水分蒸发量分别为落叶松幼龄林720 mm/a、落叶松中龄林751 mm/a，红松幼龄林762 mm/a、红松中龄林826 mm/a、柞树林677 mm/a、杂木林741 mm/a。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
