松毛虫发生世代与世代分化

本文论述松毛虫发生世代和世代分化的复杂性,包括落叶松毛虫、马尾松毛虫、赤松毛虫和油松毛虫等。发生世代因地区不同而异。在同一地区,由于松毛虫幼虫的滞育,常出现世代分化。世代分化比例在不同地区、不同年份、不同松林和不同树木之间都有差异。在同一地方,不同年份也有差异。滞育与幼虫孵化期、气候、生态条件和食料有关。本文还讨论了“油松毛虫发育起点温度和有效积温的研究”〔林业科学,1987,23(3)〕的有关问题。     

Distribution of Landscape Elements Along Environmental Gradients in Over-Cut Forests

The method of trend surface analysis was used to analyze the distribution of landscape elements along environmental gradients in Jingouling forest farm, northeast China’s Jilin Province. Results showed that topographic characteristics and disturbance pattern have much more impacts on the distribution of landscape elements than do horizontal geographical position in the study area. The elevation, slope aspect, and slope degree were found to be dominant features controlling landscape pattern. At different altitudinal ranges, the effects of slope aspect and slope degree on the distribution of landscape elements vary markedly in orientation and intensity. These differences were analyzed and discussed, and some basic rules of spatial distribution of landscape elements were proposed.

Scaling-up method for stand water consumption of Quercus variabilis water conservation forest

Single tree’s sapwood scattering style and diurnal water consumption rhythm for different diameter classes were studied in a 48-year-old Quercus variabilis stand, water protection forest in Beijing. Results showed that the tree’s sapwood area was closely related to diameter at breast height (DBH). Single tree’s daily water consumption ascended as DBH and sapwood area increased. Daily water consumption of different diameter classes in September ascended steeply in the early morning and reached the peak around 11:00, and then descended slowly to the valley at 18:00. The course of daily accumulated water consumption was in accordance with a typical Richards model (R=0.985,8). Parameters of diameter-time equation for scaling-up can be achieved by parameter-recovering method in the gradient of all diameter classes and at any time of a day, characteristic parameters of the course of daily stand water consumption were calculated from a modulated Richards equation derivative:

Empirical Analysis of the Input-Output Efficiency of Forestry S&T Innovation in China

ABSTRACT

Forestry-listed companies are important subjects of scientific and technological innovation, which play important roles in the sustainable development of forestry economy. This study used quantile regression model and least square model to analyze the input-output efficiency for scientific and technological innovation of forestry-listed companies from 2012 to 2015 in China. Regression results showed that there was no significant correlation among the variables at 0.05 level, according to the results of least square regression. And, the results of quantile regression analysis showed that under different quantiles, independent variables had a significant impact on dependent variables. This is an irrational but objective reality. Ordinary least square regression (OLSR) has some drawbacks so that quantile regression is applied, which shows a more scientific conclusion. Results indicated that: some forestry-listed companies have weak consciousness of scientific and technological innovation and lack of investment, and utility models and designs patents account for most patent applications and licensing. Also, input-output efficiency of scientific and technological innovation has not reached optimized value. To improve input-output efficiency of scientific and technological innovation, in combination with the relevant conclusions of this study, some practical and feasible measures were proposed.

Testing research for assessing suitability of multi-species of trees introduced in habitats in hilly and gully areas of Loess Plateau

To enrich resource of species, 105 arbor species (25 genera, 15 families) were introduced to the hilly and gully areas on Loess Plateau. By acclimation and selection, more than 90 tree species (12 genera, 8 families) were identified as fine species, including trees suitable for sloping fields such as Pinus sylvestri var mongolica, Pinus tabulaeformis, Platycladus orientalis, and Robinia pseudoacacia, trees suitable for gully bottoms such as Populus davidiana, Populus diversifolia, and Salix cheilophila and non-timber trees such as Prunus armeniaca, Ziziphus jujuba and Prunus persica. For those fine trees, habitat conditions and regularity of requirement of water and fertilizers were studied and then habitat ranges were given. From research results, it could be seen that Robinia pseudoacacia consumed more water, but it could improve the content of organic matters in soil; by contrast, Pinus tabulaeformis and Platycladus orientalis consumed less water and were suitable for dry sloping fields; species of apricot were suitable for sunny or semi-shady sloping fields with good conditions of water and fertilizer; species of pear were suitable for both shady sloping fields and sunny sloping fields; species of Chinese date were suitable for sunny sloping fields. __________ Translated from Scientia Silvae Sinica, 2005, 41(5) [译自: 林业科学, 2005, 41(5)]
