People living in cities nowadays have to handle the problems of air pollution, water pollution, traffic jam and land subsidence, etc.
Cities are where people can live and proliferate, we need air, water and other materials there to survive.

The main environmental problems associated with the mining activities are related to the
production of large amounts of wastes; Different pathways are responsible for heavy metals
dispersion, by air due to wind action, by water mediated by acid mine drainage and erosion, and the
metals could be mobilized in the soil by different transport mechanisms.
The transport and dispersion of contaminants can be by water, by acid rock drainage; by solid wastes as dump, heap leaching or on air pathway, by particle matter coming from copper smelters or mining dumps [1, 2].
To determine metals immobilization in the soil by effect of sulphate reducing consortium, acidified water was fed to both cubes at the top of the soil samples.
Mineral water previously boiled to remove oxygen was acidified with sulfuric acid at pH 3.0 and then at pH 2.0. pH and conductivity of eluted solution of the pilot scale test were measured and metal concentration was determinated by ICP-OES.

But because it has highly ornamental and commercial value, especially it plays an important role in soil and water conservation by the rapid vegetative propagation, so that U.
S.D.A.S.C.S. instead of the warning enlarged the planting area of Lonicera maachii Maxim. artificially as the project of funding the soil and water conservation, which more worse threaten the local ecological environment and biodiversity, until 1984, They announced to remove it form natural area by strict measures.
For the Universities, by using the advantage of professional experts and scientific equipments and cooperating with pharmaceutical companies experts to carry out the native medicinal plant research, and also medicinal components research and development on the preserved endemic plants, can help the enterprises to solve the technical problem, and also the capital the enterprise put into, can effectively compensate for the colleges and universities scientific research funds insufficiency, all these can add new vitality to further cooperation of both sides .
Guangxi medicinal botanical garden right now has introduction, cultivation and preservation of the medicinal plants more than 3193, has been called the first medicinal garden in asia, because it has most varieties of plants and is the largest professional medical plants garden in Asia Pacific region.

The cold and heat sources of central air conditioning are mainly air-cooled heat pump, water chiller unit + boiler (oil, gas), water chiller unit + central heating, lithium bromide unit and so on.
The characteristics of the method are:① The data of building energy consumption or major energy systems is from the measurement and field test;② The testers have strong professional knowledge and can correctly describe the using energy system and can correctly judge corresponding relationship between the building area and building energy consumption;③ It can identify or preliminarily determine the investment analysis of the using energy system and efficient system;④ It can only get the approximation of subsystem energy consumption;⑤ the small sample size, the long time, the high cost.
The characteristics of the method are:① Low cost;② The annual dynamic hourly load and the consumption of the air conditioning heating can be given;③ System energy efficiency and investment analysis can be judged;④ Accuracy of the method depends on the performance of the energy consumption simulation software, the input parameters setting, the field surveying, testing , simulation technology and professional knowledge.

With ever increasing requirements towards constructions evaluation regarding the building physics’ aspects, the professional public is asking the question, what is the contribution of the fastening elements to the overall value of the heat transfer coefficient U.
The next criteria to fulfill is the requirement on the lowest surface temperature in the thermal bridge spot – the fastener spot, during the winter season because of the absence of the condensation of the water vapor at the internal surface of the roof structure.
It’s the temperature at which the air is fully saturated with water vapor forcing it to change its state from gas to liquid.
Simulation of the thermal field according to models of mechanically fastened warm roofs This part of the article is focusing on educating the professional public with the simulations of steady thermal field.
