If different ecosystems are under similar environmental controls, then one would predict that the rates and patterns of response to disturbance would also be similar.
      
Because of scale effect the commonlyused measure of species diversity in terms of unit area (e.g.,species/m2) is misleading and of little use in comparing speciesdiversitybetween different ecosystems.

This paper has given 21 equations established on the basa of data obtained from 8 meteorological stations which lie on different elevations of southern slope in the middle region of Qinling Mountains. The equations show the relationship between the meteorological factors and elevations. The determinated coeffcients of all the equations are very large or large. The conditions of moisture and heat in different ecosystems of the region were calculated by the equations.

Effects of the diversified agricultural ecosystems on pest management were surveyed in the plots with different cultivation types and the fields of major agriculture region in Tibet from 1985 to 1988. The results showed that natural enemies were increased but insect pests were decreased in the diversified systems. Generally, the predacious and parasitic insects in the mixed cultivation fields were 2.3-6.0 and 1.4-2.7 times more than that in the single cultivation fields respectively. The results also showed...

Effects of the diversified agricultural ecosystems on pest management were surveyed in the plots with different cultivation types and the fields of major agriculture region in Tibet from 1985 to 1988. The results showed that natural enemies were increased but insect pests were decreased in the diversified systems. Generally, the predacious and parasitic insects in the mixed cultivation fields were 2.3-6.0 and 1.4-2.7 times more than that in the single cultivation fields respectively. The results also showed that crop yield was raised up, soil fertility was improved and pesticide application was decreased or not needed in the diversified systems. Moreover, survey on the prevalent population of living organisms and their binomics, distribution, fluctuation and immigration was done under the different ecosystems.

1985~1988年在西藏拉萨地区对不同作物种植处理并结合大田进行连续4年的调查表明,农业多样化使天敌种群数量增加,并导致害虫数量的减少。一般混作田捕食性天敌和寄生性天敌分别比单作高出2.36倍~6倍和1.4~2.7倍。多样化系统较单一系统能提高作物产量,改善土壤肥力,减少或不用化学防治等。同时还调查了主要昆虫种类及其优势种群在不同农业系统中的发生、分布、消长和转移等情况。

This experiment conducted in the four different ecosystems was to study theabsorption of organic matters in the water, accumulation of chlorine pesticidesby various aquatic vascular plants. Experimental tesults have shown that thefloating plants including water hyacinth and water lettuce have the highestabsorption rate of those wasted substances, moreover, such plants have thestrongest adaptability and easily available. Therefore, they are taken as thesuitable species used for water purification in the ecosystem engineering, whichneeds less investment facilities, but with quicker and better effects.

用四种不同生态类型的水生维管束植物分别研究其对水中有机物的吸收、有机氯农药的积累、亲巯元素(铜、铅、镉)的富集。试验结果表明水生维管束植物有较强的净化水体能力。特别是飘浮性植物凤眼莲、芜萍对以上几种污染物的吸收率高、耐污性强,且该植物生存的适应性广,并容易从水体中分离,是理想的净化品种。把这些植物应用到生态系统工程中,是一项投资少、设备要求简单,见效快的处理污水措施。
