有些非凡植物和动物还成为在中国北方生长和分布的北界，因此，具有重要保护价值。目前已开发的各类自然景观共有7种170余处，有山峰100余座，陡崖10余处，峡谷中保留了大量的地质遗迹，其中较为重要的有系统独特的地层。岩石。矿物旅游资源，典型特征的地质构造旅游资源。险峻秀丽的构造剥蚀地旅游资源。奇异多样的洞府旅游资源。得天独厚的生态旅游资源及历史悠久的人文旅游资源。

It's sure that five species are domestic animals raised by ancient settlers of Erlitou site. They are Canis familiaris, Sus scrofa domesticus, Ovis sp., Capra sp., and Bos sp..

根据所发现的野生动物的生态习性笔者推断当时的二里头遗址处在一种较现在优越的自然环境中。

The species diversity index of the Potaninia mongolica community was higher than that of three other communities and lower than that of Oxytropis bicolor community, and Potaninia mongolica, its dominant tree was stabile, therefore the community was a stabile community.

绵刺+珍珠猪毛菜+泡泡刺群落物种多样性指数比较高，生态优势度也较高，该群落比较稳定，其建群种的绵刺种群同样处于稳定阶段，所以群落是比较稳定的。

This paper deals with the classification,distribution and the phylogenetic relationships among the species of the genus Phrynocephalus in Tibet Plateau with the paleogeographic changes in cenozoic.

长期以来，对西藏地区沙蜥(Phrynocephalus：Agamidae)的研究主要是种的分类和地理分布及生态习性方面，如Blyth(1863)、Boulenger(1885)、Zugmayer(1909)、Bedriaga(1907-1909)、赵肯堂(1979，1992)、黄永昭(1979)、原洪(1986)、胡淑琴等(1987)、赵尔宓等(1993)、王跃招等(1993)等。

As a new type biological pesticide, metarhizium anisopliae （ L8500） causes no pollution, is environmentally compatible, has a low cost, clear pesticidal effects, and good economic, social and biological benefits and good prospects for promotion and application.

绿僵菌（ L8500）作为一种新型生物杀虫剂，无污染，环境相容性好，成本低，杀虫效果明显，具有良好的经济、社会、生态效益和推广应用前景。

For biogenic VOC modeling, emission factors, vegetation biomass and leaf area index were determined for 37 vegetation types. The widely accepted algorithm of Guenther et al.(1993), describing the relationship between light, temperature and the VOC emissions, was adopted. A new canopy model was established to simulate photosynthetically active radiation and leaf temperature within the canopy.

对于VOC生态源模式，确定了37种植被的VOC排放因子、生物量和叶面积指数；采用了相对成熟的关于VOC排放强度和光合有效辐射、叶面温度的依赖关系；建立了一个新的植被冠层模式以模拟冠层内PAR和叶面温度的变化。

The data showed that Phragmites communis is a plant with high light use efficiency so its reasonable exploitation can play a great role in stabilizing wetland ecosystems.

数据显示，芦苇是一种高光效阳性植物，对于其资源的合理利用及其对湿地生态系统的稳定意义重大。

Phyllanthus emblica is one of the dominant species distributed in dry-hot valleys of southwestern China. Besides its function in ecology, environment and reforestation, it is also an important medicinal plant.

余甘子是我国西南干热河谷地带的优势植物，也是一种重要的药用经济植物，对其遗传多样性进行研究对生态环境的建设和恢复有着重要意义。

According to the phytosociological theories and methods of Braun-Blanquet's school, the regional savanna vegetation of the dry-hot valleys of Yuanjiang river had been investigated. Based on the principle of fidelity degree, the typical 110 releves taken from every sampling stands of the dry-hot valleys were sorted up from below to upper into 15 Associations, then into 5 Alliances, 2 Orders and 1 Class. A synoptic classification system of Class-Order-Alliance-Association was established for the purpose to reflect deeply the characteristics of all syntaxa there in the aspect of plant component and their abundance-dominancy, presence, cover coefficient, life form, growth form, and ecological environment, community structure, species types and so on.

采用Braun-Blanquet植物群落学研究的理论与方法，对云南元江中上游干热河谷分布的植被进行考察研究，把各处取得较典型的110个样地记录按确限度的原则由下而上归类成15个群丛、5个群属、2个群目和1个群纲，建立了元江干热河谷萨王纳植被群纲—群目—群属—群丛分类系统综合表和15个群丛表，以全面深入反映全干热河谷植物群落各级分类单位中各植物种类组成的多优度、存在度、盖度系数、生活型和生长型等特征及其群落结构、生态环境和种型类别。

Peanut or rice wereplanted in the large-scale weighing Lysimeter,pit plots,and standard runoff plots,wherehigh,moderate,and low soil moisture levels were designed as 3 treatments,assemblingwith some instruments such as time domain reflectometry,portable photosynthesis system,dew point microvoltmeter,and porometer.

季节性干旱缺水严重制约着我国红壤区农业的持续发展。1999～2000年在中国科学院红壤生态实验站，利用大型称重式蒸渗仪、测坑小区和径流小区，配合时域反射仪、光合蒸腾仪、水势仪及动态气孔阻力计等仪器，设计高、中、低3种土壤水分处理，进行了花生和早晚稻试验。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
