Seawater samples with ball cap Q2-3 type water sampler, according to the surface, 25, 50, 100, 150 and 200m 6 levels collection, to analysis water temperature, salinity and concentration of nutrients.
Micro phytoplankton samples were treated with capacity of 5dm3 ball cover type organic glass water sampler collecting 6 levels of Water 500ml and silk screen mesh hole width 64mm, the diameter 37cm, long 270cm, net hole area made of 0.1m2 phytoplankton standard small network, used as vertical drag collection from 200m water depth to 0m.
Collected sea water samples were filtered by Whatman GF/F glass fiber membrane (pre burned for 2 hours in 450°C).
At the Antarctic convergence zone to the south, under the influence of water seepage, exchange, water temperature and salinity of the sub Antarctic obviously decreased, promoting the growth of photosynthetic plankton, average value of Chl a concentration ratio is about 6 times higher than subtropical water concentration.
Chl a concentration in the shelf area is higher, and it’s limited in the water shallower than 25m.

In 2007, Urumqi government reformed its MSW treatment fee system, because of the low percentage charges level of MSW treatment fee before, from 3 RMB fixed fee per person per month to water consumption based fee system.
For example, when the residents consume 1 m3 water for household use, 1 RMB of MSW treatment fee will be charged; for commercial use, 0.8 RMB will be charged.
However, this amount of budget is accordance with the water consumption of the residents, not the MSW generated amount and related service.
The huge amount of leachate, which couldn’t be treated in time, may badly pollute the nearby underground water, soil and air, endangering people’s health.
While credible and valuable data are obtained though scientific research, fruitful and constructive ideas related to MSWM could be provided by professionals, which could unquestionably improve the general efficiency of MSWM.

In Western countries which are mainly private property rights, there are some natural resources, such as land, forest, mining, water, etc. which are owned privately.
If the atmosphere contains dust, it can be purified by spreading with air currents, precipitation leaching and gravity sedimentation, after the sewage flow into the rivers and lakes, it can be purified through adsorption, precipitation and water dilution, proliferation, the content of volatile contaminants in the soil, such as phenol, cyanide, mercury, etc. can be gradually decreased due to volatilization.
For example, some organic contaminants ultimately generate water and carbon dioxide by oxidation, reduction, copper, lead, zinc, cadmium, mercury and other heavy metal ions in water compounds with sulfide, generate insoluble sulfide precipitates, these are all the chemical purification of the environment.
Plants absorb phenol, cyanide of soil, then transfer them to sugar glycosides and cyanide glycosides, sphaerotilus decompose phenol, cyanide into carbon dioxide and water, green plants release oxygen under the photosynthesis.
Environmental compensation projects authority is responsible for accepting the projects of environmental compensation, but after compensation construction activities for the subject of environmental remediation, whether the purposes of compensation according to project contracts are completed, how effective the compensation is, these should be evaluated by detection of specific environmental quality, evaluation organizations, base on the request of professional, technical division of labor and management of constraints within the organization to contain and prevent rent-seeking.

A lot of technology problems are not existing within the professional domain of architecture, such as energy optimization, sewage treatment, use and treatment of solar-energy, which need the cooperation of architects and other engineers.
Sapporo Dome’s huge silver gray dome roof has its own feature, just like a huge “bubble” floated in the air or a huge water-drop lies quietly on the earth, concise and fluent shape is similar with the scenery in Hokkaido vast (map 3).
recycling reclaimed water, subsided layout the topography and landscape geothermal energy groundwater snow and water the reclaimed water utilization snow and rain water the use of natural light skylight lighting air vent the indoor wind field the use of natural ventilation Map 10：The Diagram of Public Buildings’ Eco-design in Large Space Conclusion By the analysis of main strategies of eco-design of public buildings in large space, presenting comprehensively its basic concepts and aims.

New hospitalization department mansion adopts "air and water" central air condition system, whole years in addition to 4, in May and 9, adapt from because the weather is cool in October however in addition to airiness, the rest month all adopts central air condition system.Lately set up a hospitalized department mansion sickroom the air condition circulate the new breeze compare to 0.2.Press and use to request according to the air condition to periodically make to clean, disinfect completely from the professional personnel.
The air condition designs medium should notice: dark the coagulation water dish of dish tube packing breeze machine have to keep to condense water to drain lucid, the cancellation saves water cave slot; The breeze machine dish tube machine set in the sickroom should install in the place of keeping off the patient possibly, in order to prevent the dust cleaning up a filter fly to spread.
Suggest an air condition to condense water at the same time at has been disinfected and handled after again carry on emissions.

Baishuihe landslide has occurred several deformations since the professional monitoring implementation.
The underground water level fluctuation is the comprehensive response of rainfall and reservoir water level.
The raise of underground water replenished by rainfall increases pore water pressure and leads to the change of hydrodynamic condition [10].
Curves of rainfall, reservoir water level, underground water level and landslide displacement Prediction of landslide displacement based BP neural network Mentioned before, select the rainfall, the water level and underground water level as influencing factors to predict relative displacement based the monitoring data of ZG118 from January 2005 to May 2009.
Through the analysis of landslide deformation characteristics, established the prediction model of landslide displacement based on rainfall, reservoir water level and underground water.

Open space is a land and/or water area with its surface open to the sky, consciously acquired or publicly regulated to serve conservation and urban shaping function in addition to providing recreational opportunities" (Marilyn, 1975).
But Tankel (1963) has another opinion, namely that open space is not only the land, or the water on the land in and around urban areas, which is not covered by buildings, but it is also the space and the light above the land.
Though it is always ignored by professionals, politicians and decision makers for the street that acts as the boundary between public and private life, it impinges upon urban life as routes, locations for services and frontages to both residential and business properties (Institute of Civil Engineers, 2000).
