Habitat selection of goral was mainly influenced by distance to human disturbance, altitude, distance to forest edge, distance to water source, slope position, shrub canopy cover, shrub height, level of concealment, slope aspect and wind direction.

因子分析表明，影响矮岩羊生境选择的主要因子为人为干扰距离、海拔高度、林缘距离、水源距离、灌丛高度、隐蔽级、风级和动物干扰距离等生境因子，而影响斑羚生境选择的主要因子为人为干扰距离、海拔高度、林缘距离、水源距离、坡位、灌丛盖度、灌丛高度、隐蔽级、坡向和风向生境因子。

The results are listed as follows:(1) In peneplain with plenty water-resource, hexagonal spatial structure of urban system can be formed. Due to differential competed function of central places, the hexagonal system is distorted. The result is that the area covered is decr eased and the girth is unchanged——but every border is usually unequal;(2) A pattern of pentagonal system evolves from hexagonal system controlled by a river;(3) A pattern of quadrilateral develops from hexagonal system under two parallel rivers;(4) The equal distance distribution of central places in narrow geographic space has its special reasons. The results are very important for understanding urban's formation and development and urban plan in Huang-Huai-Hai plain.

本文通过自然地理因素中水文、地形这两个重要要素对城镇体系空间结构形成的影响，分析了华北平原区在不同要素影响下的城镇体系空间结构样式：①在水源充足的准"均质"河北冲积平原上，基本满足六边形形成条件，但由于周边中心地发展竞争力不同，故使得正六边形发生畸变——覆盖面积减小而周长却保持不变；②构建了在一条河流影响下的六边形网络结构朝五边形网络演变的模型；③构建了在平行状河流作用下六边形网络向四边形网络演替的模式；④指出了在水源充足的狭长地理空间，城镇体系空间结构发育成等间距的现象与原因。

It is a new vacuum mair pump,which can provide with circulating water to the reaction of device at same time.

同时还能向反应装置中提供循环冷却水，特别是在水压不足和缺水源的试验室更显之优越。

Ten million will go to drill for water and regrow paster lands,the other money will go to cattle producers to help them recover their loses from selling early.

那就意味着农民们面对的是低成本的紧急负担。但是他们正在向国会申请额外的1700万美金作救济金。其中1000万是用来引进水源，其他的用来重建牧场。

Immoderate discharge of mine water not only wastes a great deal of precious water resources, but also increases the cost of per ton coal and causes some environmental problems such as ground collapsing, ground water resource loss, water quality deterioration and so on. Therefore, rational utilization of mine water as resource is the best choice of solving the water source problem of mine site and pithead power plant and the environmental problem of mine water pollution.

本文在分析彬长矿区地质及水文地质条件的基础上，分别用"大井法"和水文地质比拟法计算了亭南井田、大佛寺井田、胡家河井田和小庄井田四矿的矿井涌水量，分析四矿矿井向大唐彬长坑口电站的供水能力，并对矿井水的水质进行了评价，研究了矿井水作为电站供水水源的可行性。

According to the United Nations, 95% of the world's cities still dump raw sewage into their water supplies .

据联合国宣称，世界上95%的城市仍然在向他们的水源倾倒下水道垃圾。

There are several factors including average altitude, southern slop of hills,gentle slops, under branches, southern Orientation of nests, near to water, nearby places for sandy bathing and covering woods nearby nests that decide the nesting selection of blood pheasant. There are significant differences among the nests of blood pheasants on the nearby vegetation in spite of arbor, shrub and herbage.

作者在血雉产卵期（4.28—5.9）采用跟踪调查的方法，对其巢穴与栖息地生境因子选择进行了调查，结果显示血雉巢穴选择主要生境如下：平均海拔2700米左右、梁下部、南坡、坡度平缓、巢向南、距水源近、巢周围有栖材，有能够用来沙浴的地方，位于树根、树桩下，防风雨、巢材是竹叶、树叶。

From my two field surveys to the hinterlands in 1987 and 1995, respectively, I was shocked by the facts that swidden agriculture still prevailed widely, and some of the villages faced serious soil erosion and water shortages arising from traditional practices.

乡村景观的实地考察说明：这些地区刀耕火种、轮歇耕作仍然盛行，不少居民已经面对着农牧业用地向林区过度扩张所致的水土流失、水源枯竭等严重环境问题。

Water originates mainly from the Soviet Union, Mongolia and China border Tannu Shan (friendship peak 4374 meters) in two small rivers, the water flows south and a small tributary of the Irtysh River, the lake has a narrow strait sedge, grasses swamps, surrounded by Europe, the extension of the Siberian taiga south, spruce, larch, Xinjiang, Xinjiang red cedar, fir, Pinus forest, etc. there is moss and Hagoromo grass, water, etc. Ranalisma. After the Xinjiang Uygur Autonomous Region in 1980 approved the establishment of nature reserves Hanasi (has been approved as a National Nature Reserve).

水源主要来自发源于苏联、蒙古和中国边界的唐努山（友谊峰4，374米）的二条小河、出水向南流入额尔齐斯河的一条小支流、湖的两岸有狭窄莎草、禾草沼泽、四周有欧洲、西伯利亚向南延伸的泰加林、云杉、新疆落叶松、新疆红杉、冷杉、五针松等林下有苔藓及羽衣草、水毛茛等。1980年经新疆维吾尔自治区批准成立哈纳斯自然保护区（已被批准为国家级自然保护区）。
