结果表明，按其影响程度大小，影响中国翼手目动物地理分布的连续型环境因子依次为年平均气温、大于零度日数、一月份平均气温、无霜期日数、年降雨量、年平均相对湿度、七月份平均气温、海拔高度和年日照时数，其中年日照时数和海拔高度为负影响；影响翼手目种数密度分布的决定环境因子是年降雨量，但年平均气温也有明显作用。

Take Zanhuang County in the eastern part of Taihang Mountains,as an example, the author chose the data of the annual mean precipitation by the hydrometric station of this county and the meteorological stations nearby from 1971 to 2000 and the longitude, latitude and altitude of each station as the study objects.

以太行山东麓的赞皇县为对象，选取1971～2000年该县水文站和周围气象站的年平均降水量，以及各站的经度、纬度、海拔高度等资料，采用回归分析方法，建立了年降水量的不同形式的空间推算模型，并利用3σ规则分析了各模型的海拔高度适用范围。

It is theoretically demonstrated that the influences of terrain height and orographic heterogeneity are important on the flux of surface long wave radiation over a large scale grid area.

摘要从理论和数值试验两个方面证明地形的非均匀性对网格区地面长波辐射通量的计算有重要影响，海拔高度场的区域平均值及其变差系数是影响网格区地面长波辐射通量的主要因素，仅仅用地表均匀假定下的区域平均参量（如平均海拔高度和平均温度）所计算的网格区地表有效辐射通量值与其真实值之间存在着一定的误差。

Therefore, we selected common species of Ranunculaceae. comparative primordial plants in Alpine Meadow at Eastern QinghaiTibetan Plateau, and studied the reproductive strategies, such as reproductive allocation, especially sex allocation, to understand how the plants adapt the environmental conditions. The results showed:(1) At higher altitude, the self-incompatible plant, such as Trollius ranunculoides tended to become limited by pollination rather than by nutrient availability, while the self-compatible plants, such as Anemone rivularis and A. obtusiloba seemed not to be limited by pollen availability, which suggested that ability of self pollination for alpine plants may be a mechanism of reproductive assurance.(2) Influences induced by high altitude on the reproduction of these species occurred on different reproductive characters, which suggest species-specific adaptive strategies. The influences are dependent on plant size to some extent.

因此，我们选择在青藏高原东部的高寒草甸，以比较原始的植物类群—毛茛科植物为研究对象，选择一些常见种探讨其繁殖对策，如繁殖分配和性分配问题，试图揭示这些植物如何适应环境条件，最后的结果表明： 1高寒草甸高海拔区，自交植物(如小花草玉梅A.rivularis和钝裂银莲花A.obtusiloba)的繁殖不受花粉限制，而完全异交植物(毛茛状金莲花T.ranunculoides)的繁殖受花粉限制，表明高海拔地区植物的白花授粉能力可能是一种繁殖保障机制，能够避免恶劣环境对植物有性繁殖的不利影响； 2海拔高度对植物的影响因种而异，不同的物种受影响的繁殖性状不同，即使同属亲缘种间也存在差异，表明不同物种对相似环境压力的适应对策不同；而且，海拔高度对植物的影响在一定程度上依赖于植物个体大小，说明植物通过调整其个体大小与繁殖性状的关系来适应环境梯度的变化； 3植物花期和果期的繁殖分配并不完全随海拔升高而减小(只有小花草玉梅的果期RA随海拔升高而减小30％)，与Iwasa和Cohen的预测不完全一致(他们认为繁殖分配随生长季缩短而减小)。

A relationship between the frequency of occurrence and diversity of AM fungi and the elevation of the sampling sites for Swietenia macrophylla was observed. The elevation significantly affected the frequency of occurrence and diversity of Gigaspora and Scutellospora, but showed no significant influence to Glomus and Acaulospora.

通过对不同海拔高度Swietenia macrophylla根际AM真菌分布的分析表明，海拔高度显著影响着AM真菌的分布，Gigaspora属的真菌随海拔高度的增加显著升高，Scutellospora属的真菌则显著降低。

It is the biggest that slope direction impacts on the temperature in four factors ——underlaying surface, slope direction, slope position and altitude.

下垫面性质、坡向、坡位和海拔高度四个因素中，坡向对温度影响最大，其次是海拔高度，坡位和下垫面性质影响较小。

During the summer (1st to 6 th June)and the winter (10 th to 17 th December) in 2005, a survey of the bird communities were conducted in Dapanshan National Nature Reserve by the methods of line transecting and point counting. Along several transecting lines, we chose enough fixed-radius counting points according the altitudes and the habitats.

2005年，在大盘山国家级自然保护区区域范围内，根据自然景观地貌确定一定数量的样线，在每样线上根据不同的生境和海拔高度有针对性地选取一定数量固定半径的调查样点，调查每一样点鸟类的种类和数量以及生境类型和海拔高度。

The diversity indices of communities located between 1400 and 3600m of theTaibaishan,the highest peak of Qinling Mountain Range located in the southern edge ofthe WTZC,are studied based on data from 55 quadrats.

对秦岭主峰太白山海拔1400-3600m之间植被类型和物种多样性进行了研究，在划分的15种群落类型中，以位于海拔1500-2300m之间的落叶阔叶混交林和栎类混交林的群落多样性最高，在海拔2300-3600m之间，群落多样性趋于单调下降，反映了熟量的不足在这一海拔高度范围成为多样性的主要限制因子。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.
