For the water quality evaluation in park, the water samples are uncertain in both morphology and category because of their uncertain properties.
This work studied the water quality evaluation in three parks of Changchun, China by applying the water quality evaluation in park based on similarity measure of Vague sets.
Summary According the water sample data at sampling points of three parks in Changchun, the evaluation results of samples to be evaluated are Class II, unpolluted water for one spot and Class V, heavily polluted water for two spots with the pattern recognition method of Vague set based on similarity measure, which is basically consistent with evaluation of professionals in Reference [11].

(2) Strengthen the propaganda and training on green building knowledgeRegular organization of administrative departments, supervision of law enforcement agencies and construction units, design units, construction units, supervision units in the green building policies, regulations, standards, technology and professional training to enhance the ability and level of professionals.
Strengthen green building regionalization qualified access to the development of the whole process, including planning, design, construction, construction, evaluation, operations, consulting practitioners main practitioners qualification system, green building is included in the assessment of professional qualifications and continuing education assessment to improve the professional quality of the green building professional technical and management personnel, to strengthen the capacity building of green building design, construction, operation, and evaluation.
Water, also known as reclaimed water, its water quality ranged between sewage and tap water, urban sewage, waste water purification treatment to meet the national standard, non-potable water can be used within a certain range, can be used in the urban landscape and the people living many aspects.
Meanwhile, the sewage treatment plant is renewable water sources, regeneration and urban water users in a relatively short distance, convenient water supply.
So, take full advantage of rain and water, you can save water and protect the environment.

Findings of empirical survey conducted among professionals such like Architects, Engineers, Quantity Surveyors, Builders and Contractors practising in some selected cities in Nigeria on the use of the material were analysed along side with personal interviews of these professionals to obtain their views on the subject, revealing that the industrial production of standardised wood-based material to a finished stage makes building operation faster, reduces labour and wastages and enhances modular designs and construction thus aligning production with the current global trend.
Others include materials efficiency, elimination or reduction of generated waste; low toxicity; water conservation; affordability.
The variables, structured in question form, written in English language, and responses required in pre-coded alternatives given were targeted to elicit opinions of professional on the use of these materials.
Research assistants, who had earlier been trained by the author, administered the questionnaire to selected professionals (Architects, Engineers and Quantity Surveyors) distributed over four out the six geo-political zones in Nigeria.
The cities were purposively selected as places with high concentration of these professionals practicing in Nigeria.

Introduction
Water pollution, change of physical, chemical, and biological properties due to materials mixing in water, affects living things in the water.
The use of water sources is not only limited by quantity but also by quality of water.
Therefore, it is necessary to trace the amount of water and its quality in terms of protecting “utilizable water” [2].
One of the most important reasons for pollution of groundwater in China is water supplementation of surface waters.
Therefore, water pollution control is quite important, which need special professionals to carry out water treatment and protection.

Correlation between carbon emissions and building design
Ancient building construction was solely completed by craftsmen, with no professional division.
However due to the development of modern architecture interior space requirements, even a simple building design should be completed by many professionals such as architect, structure engineer, electrician, and water supply and drainage designer.
According to the requirements, the environmental conditions and relevant laws and rules, all of the above professionals complete a building design altogether.
Fig. 1 Correlations of building design and carbon emissions From Fig. 1, it is obvious that each professional is relevant to building carbon emission.
Building structure gives us space indoor, we also need some equipment such as lamp, HVAC system, water plumbing to make interior space better for living.

As the main course of professional engineering supervision, Engineering Detection Technology is a course which equally emphasizes both on the theory and practice.
Introduction The engineering detection technology of Project management is a major professional course, its main task is to make the students consolidate and deepen the understanding of engineering detection technology.
Engineering testing technology course content is multifarious and lack of systematic, continuous, which if taken under traditional teaching mode ,the students feel dull as ditch water and their study interest is not high.
At the same time, with high professional quality for a teacher, regardless of expertise or in the cultivation of humanities on the proposed high demands.

The Analysis of Urban Water Conservancy Project Function
Water and city phase is tightly quoted, to make the harmonious development between city and water is the intrinsic requirement for modern city construction of urban water conservancy.
Part of the water affinity platform is covered wood, it can apply colors to a drawing the water warm atmosphere and beautify the image of the water.
Planting some lotus in shallow water, Persons should be warm feeling when walk around water affinity platform.
If the plants on the ecological revetment going to wither or pathological change, it will influence the stability of bank slope, therefore, it need to be done by professionals follow-up maintenance and management, so as to play a water conservancy project of the ecological environment function boast skillful.
Based on the function of water resources comprehensive utilization of city water conservancy engineering research [J].
