Most environment pollutions appear mainly in karst region,especially in the form of water pollution; environment pollution has a much worse destruction to the earth,vegetation and physiognomy,especially in the quarry areas. It even results in geologic hazard; for the mine geologic hazard,the background of physiognomy is the potential factor,while the irrational exploitation is the magistral factor.

环境污染多出现在岩溶地区，以水污染为主；环境资源的破坏以露采区最为严重，对土地资源、植被、地貌景观有较大的影响，甚至对地质灾害的发生都有深刻影响；矿山地质灾害的发生，地质地貌背景是诱发的潜在因素，不合理的开采方法是诱发的主导因素，降雨和水文条件是激发灾难发生的直接原因。

According to basic analytical methods of environmental quality standards for surface water in China(GB3838-2002),we used the 2002-2006 monitoring data to evaluate and characterize water quality condition of Lanzhou reach of Yellow river,based on the Nemerow index and variance analysis of the mean square deviation.

根据2002-2006年黄河兰州段水质监测数据，按照《地表水环境质量标准》GB3838-2002中Ⅲ类水质标准，确定污染物的污染程度，选用内梅罗水污染指数法，运用方差分析，对黄河兰州段水质现状进行评价分析，结果表明：(1)黄河兰州段水体的主要污染物是粪大肠菌群和总氮；(2)大量未经处理的生活污水排放是黄河兰州段的主要污染源；(3)针对黄河兰州段生活污水污染现状，提出源头治污思路。

Intentionally or negligently, the third party shall be liable to makecompensation.

To find out the substitute parameters for pathogenic microorganism warning aiming at potential pathogenic microorganism pollution accidents happened in water environment,the relationships between turbidity ,particle counts and concentration,removal,recovery rate of Giardia cyst and Cryptosporidium oocyst in raw and filtered water are presented.

针对潜在的病原微生物突发性水污染事故，为寻找病原微生物预警替代性指标，重点探讨浑浊度、颗粒计数与原水、过滤水中贾第鞭毛虫孢囊和隐孢子虫卵囊浓度、回收率、去除的关系，认为浑浊度与颗粒计数可以作为水厂处理效果与饮用水受两虫污染的指示指标，并结合水厂的实际情况提出相应的控制方法和建议，指出暴雨时应特别注意两虫的爆发

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.
