    Simulation model of brown planthopper ( Nilaparvata lugens Stal ) on rice was constructed using intensive field observation, together with data obtained from the literature. The physiological time was adopted in the model. The main components include the time, size and parttorn of immigration! the effects of density, variety, crop stage, temperature and age on fecundity; the effects of density, crop stage, high temperature, natural enemies and artificial measures on mortality; the relationship of prorortion brachyptcry in adults and emigration to density and crop stage. Validation showed that the simulated dynamics of population time and size were similar to the observed ones, and that simulated peak times and 9 simulated peak sizes of main damaging generation in 10 sets of data were close to those observed. The comparison of discrepancies between simulated and observed population dynamics indicated that a thorough study on the continued effects of low temperature on fecundity and mortality in autumn, the quantitative relation between planthopper and natural enemies in fields and rice growth model was conducive to the understanding and forecast of the population dynamics.

    Arrow Bamboo (Bashania fangiana) only distrbutes in the western mountains of the Sichuan Province, growing in the mixed forests of coniferous and broadleaf trees and under subalpine needl forest at about 2100—3600 metres above sea level. This kind of bamboo in Qionglai mountains is Giant Panda's staple food. In 1983, Arrow Bamboo was flowering, seeding and dying-off, and the flowered area was about 65 to 95 percent of the total area in which Arrow Bamboo distributed. Aecording to the history, Arrow Bamboo flowers every 50 to 60 years. It will take over 10 years for the seed to become adult bamboo. As a result, the Giant Pandas in this area have a periodic food crisis. Therefore, studying the seed charaeteristics and the regeneration of the seedlings and using some methods to improve their regeneration and rehabilitation are not only the need of the study on its characteristics of bio-ecology, but also strategic measures. for the research, conservation and population development of Giant Pandas. This article describes the characteristics of the seeds of Arrow Bamboos: net percent, water containing, weight of 1000 seeds, living ability, rate of sprout, resting period and life span of the seeds. It also describes the growth of the bamboo seedlings: seed quantity on the ground during the natural regeneration; lasting time of the sprouts; growth of the seedlings; seedling amount trends in the early period of the regeneration; the rate of the living seedlings; and the growth and changes of the seedlings. So the general principles of the life activity of the seeds and the growth of Arrow Bamboo seedlings have been found, providing the Scientific basis for artificial improving Arrow Bamboo's natural regeneration in high mountains.

    冷箭竹(Bashania fangina)为四川西部特产,分布于海拔2100~3600米之针阔叶混交林和亚高山针叶林下,是邛崃山系大熊猫的主食竹种。1983年,该竹种发生大面积的开花、结实而枯死,开花面积占竹子分布总面积的65~95%。据史书记载,冷箭竹的开花周期为50~60年。竹种萌发成林约需10年以上时间,从而导致以此为食的大熊猫发生周期性的食物危机。因此,研究冷箭竹的种子特性及幼苗更新规律,采取人为措施加速幼苗的更新复壮,这不仅是研究该物种生态生物学特性的需要,也是保护大熊猫,促进其种群繁衍的主要途径。本文描述了冷箭竹种子的净度、含水量、千粒重、生活力、发芽率、休眠期和生命期限等特性,并介绍了该竹和在自然条件下林地上的种子数量、种子发芽持续时间、幼苗更新的期数量的动态变化、幼苗成活率和幼苗的生长变化。通过这些研究,初步掌握了冷箭竹种子生命活动的一般规律和幼苗生长的基本特征,为提高高山地区冷箭竹的自然更新能力提供了科学依据。

    The soil water cycle level can be defined as the average state of soil water fluctuationin a given period of time.It can be employed as an indicator in assessing the soil water cycle sta-tus. Even if the soil water cycle strikes balance in a given period of time, it does not always meanthat the water cycle remains in an optimum status. It is necessary to take both the water balanceand the water cycle level into consideration at the same time in order to assess whether the watercycle remains in an optimum status.To some extent,the soil water cycle level of an ecosystem canbe regulated by taking some artificial measures.

    土壤水分循环水平是指一定时期内土壤水分波动变化的平均状态。它是判别土壤水分循环状况优劣的标志之一。土壤水分循环达到平衡状态,并不一定说明土壤水分循环处于最佳状态。只有同时对土壤水分平衡状况和水分循环水平进行分析,才有可能作出可靠的判断。在一定程度上,生态系统的水分循环水平可以通过人为措施来调节。
