Different climate change in west and east part of north China in recent years is major reason for this phenomenon, not vegetation cover, but degenerated vegetation cover, corresponding to abnormal droughty climate during these period, is one of reasons for abnormally high dust activity in the end of 9Os'in Huabei Plain.

九十年代末，对应于我国北方地区，特别是华北地区干旱少雨的气候条件，植被覆盖状况有明显下降的趋势，这可能是世纪末华北地区沙尘活动频繁的一个重要原因，但我国西部沙尘源区沙尘气溶胶光学厚度仍然保持继续下降的趋势。

It is found that two osillation periods role for UT atmosphere components changes, i.e., 10-20 dyas and 30-60 days, while the intra-seasonal oscillation period for LS is 30-60 days.

南亚高压主体的东南侧为强的上升运动区，此大气流场的气候态特征为对流层向平流层水汽输送提供了有利的环流背景条件。

Study on the driving forces of land use/cover temporal-spatial change. On the basis of the systematical study on natural and social-ecomic factors including climate, population, technology and affluence status etc. during the past 50 years in this area, the multivariate statistics simulation models of LUCC were developed for two periods of 1950's-1980's and 1986-2000 respectively. Then, the Thiesson polygon method was used to the spatial allocation of soci-economic factors, thereby the spatial relationship between land use degree change and socieconomic factor variation was detected within GIS. Based on the analysis of the integrative characters in different geographical divisions, the electivity index was employed to describe the possible impacts of the natural landscape structure on spatial differentiation of land use transition. At last, correlation analysis between major roads and the distribution of land use change was made.

分析近50年气候资料和人文因子在不同年代的变化特点，系统地研究了气温和降水等自然因子和人口、农牧业发展、经济状况等人文因子对区域土地利用变化的影响；从时间序列的角度分析了50年代至80年代初和80年代中期至2000年两个时段土地利用／土地覆被变化的驱动因子，在相关分析的基础上，分时段建立了区域土地利用／覆被变化的自然-人文影响统计诊断模型；针对不同经济类型区选择典型县，分析近15年土地利用变化外在人文驱动力的区域相似性和差异性；尝试以THIESSEN多边形方法进行社会经济统计数据的空间化处理，探讨了土地利用程度变化与人文因素变化的空间相关关系；以优先指数模型和土地利用类型转化率与距交通干线距离的相关模型分析了景观自然与人文结构对土地利用空间转化过程的影响。

The composition and the faunal distribution of fleas are chiefly determined by their host animals and the zoogeographical distribution of the latter is in turn determined by vegetation climate and landscape as well as other geographical factors such as latitude and elevation.

蚤类的组成及区系分布主要决定于它们的宿主动物，而后者的动物地理分布又依次取决于植被、气候、景观及其他地理因素如纬度、海拔高度等。

And also the things such as the size of provenance zone,genetic characteristics ofprovenance,climate condition and forest feature will provide a reference basis forhow to transfer seeds,how to make genetic improvement program and how tomanage the seed production bases.

各种源区的范围、遗传特点、气候与森林特征等可作为长白落叶松种子调拨、制定遗传改良方案和良种基地布局的参考依据。

In arid climates, surface water is generally better than ground water in headwater areas, but poorer downstream.

在干旱气候的上游区，地表水一般较地下水好，但下游的地表较差。

Based on spatial pattern of physical environment and socioeconomic status, the causes of desertification in the headwater area of the Yellow River are discussed using geographical information system and remote sensing.

根据黄河源区的自然环境条件、社会经济发展状况，在GIS的支持下对沙漠化发生发展的物质条件、气候条件以及人类活动等影响因子的空间格局特征、规律和变化趋势进行了定量分析。

Climate and soil factor of Catanopsis hystrix native forest in fifteen countries were surveyed, results showed that Distribution area of Castanopsis hystrix native forest in Gangxi belongs to south subtropical seasonal wind climate, and Castanopsis hystrix native forest in the forest mainly was representative types of south subtropical seasonal rain forest and ever - green broad - leaved forest in China.

通过调查统计广西15个红锥天然林县市的气候和土壤因子，结果表明广西红锥天然林分布的地区属南亚热带季风气候区，以红锥天然林为主的森林是我国南亚热带季雨林化常绿阔叶林的代表类型；红锥天然林分布以赤红壤、红壤林地出现较多，土壤酸碱度为微酸性（pH4.36～6.23）。

The reconstruction of past variations in lake level, water chemistry and limnological conditions may provide key site information on the post-glacial climate change of the region.

重建黄旗海水位、水化学和湖泊生物学变化历史可为研究我国夏季风边缘区冰后期气候变化提供重要环境记录。

The south sites locate on subtropical monsoonal climate region, which vegetation types mostly are evergreen vegetations and the start and end of growing season are not obvious. Therefore, BGP and EGP estimated by the model are not the real start and end of growing season, but reflect vegetation's response to regional climate changes.

这是因为南方站点地处亚热带季风气候区，地表以常绿植被为主，植被生长季开始与结束日期均不明显，因此遥感监测的并非真正意义上的植被生长期始末日期，而是植被对区域气候因子变化的响应状况。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
