Abstract: This first survey in 2009 and 2010 on silica-scaled Chrysophytes in Zhenbao Island Wetland Preserve, Northeast China, recorded 32 taxa (5 in Chrysophyceae and 27 in Synurophyceae), of which 29 were previously found in other parts of China, three species, Spiniferomonas serrata, Mallomonas transsylvanica and Synura punctulosa are new records to China. In terms of biogeography, 1 taxon is endemic, 2 bipolar, 1 northern temperate, 9 cosmopolitan, and 18 of wide distribution. The endemism of Synura punctulosa, appears due to its poor dispersal ability; lack of sampling data may also contribute its known distribution range. Spiniferomonas serrata and Mallomonas transsylvanica, two bipolar taxa, are the first report in China. More research efforts are needed for adequately understanding the distributions of this group of algae.

Abstract: With the point source pollution was effectively treated, non-point source pollution, especially the agricultural non-point source pollution (ANPSP), is becoming the main problem in environment. The research is focused on the model analysis and application, which could be scientifically distinguish and effectually control ANPSP. Four kinds of models were introduced here with the development of non-point source pollution, as experience statistical model, mechanism model, function model, improved model by 3S technology and the uncertain analyze. Among these models, HSPF and SWAT model were successfully applied in best management practices (BMP) for ANPSP control. In the future, our country should base on the introduction of the foreign mature techniques, which combine the 3S technology and the uncertain improved model, then enhance the autonomous model research and build the basic database.

Abstract: Agricultural nonpoint source pollution (ANPSP) is an important source for water environment, with its contribution ratio increases year by year. ANPSP becomes the environmental bottleneck factor in restricting agriculture sustainable development and rural modernization. The study was focused on the causes and occurrence of ANPSP in the middle region of Zhejiang province, and introduced some successful governance effect of best management practices (BMP) in developed region. The application of control technologies under BMP guidance were compared and analyzed, among artificial wetland, front library, buffer zone and land-water interlace belt, water and soil conservation, agriculture ecological engineering management and so on. According to the characteristics of different BMP technologies and ANPSP in the middle region of Zhejiang, the regional BMP should be designed for solutions. This research made good sense to promote effective control of ANPSP in middle region of Zhejiang in engineering application.

Abstract: The thesis attempt to illustrate two things and their relationship in the city— industrial heritage and ecological urbanism— by focusing on the transformation in industrial heritage site. It starts with the definition of industrial heritage and quarry what is prepare for the later dissertation. From the theory to the case, this thesis tries to explain the questions: How the industrial element and ecological element work on the city together Why propose in industry heritage site Why it needs to be changed After finding its potential and disbennifit, paper gives the answer that how to changes. Finally, the proposal in Lockport is introduced as a case for the ecological transformation strategy of industrial heritage site.

Abstract: The rapid development of high-rise buildings has brought difficulties to urban environmental safety. Fuzzy evaluation method is adopted to conduct qualitative and quantitative analysis of Baotou's high-rise architectural environment through a close combination of the course and the cutting-edge technology of the scientific development of architectural environment. The analysis is implemented in three aspects including body safety, resource safety and social ecology safety. It also analyses the practical situation of Baotou's high-rise architectural environment through real cases, hoping to provide theoretical direction for the improvement of Baotou's urban environmental safety.

Abstract: Pumpkin is one of the major vegetable crops in cucurbit family. Due to its easy cultivation, high yield, long shelf life and abundant nutriments, pumpkin is very popular in China. In this paper, we study on the germplasm development and innovation of high quality edible pumpkin: Halixiang NO.1. We also discussed the species quality, characteristics and field management.

Abstract: A whole process chain managerial strategy is presented to solve the problems of sludge treatment and disposal of municipal wastewater treatment plants in a city of northern China. The problems include negligence of the sludge treatment, scarce capacity, ambiguous responsiblity, lack of whole process management and coherence of management on wastewater and sludge treatment. The system of whole process chain managerial strategy can provide a safe and effective platform to collect the relevant data about sludge disposal. In the system，all executants have the obligation and responsibility to record the data, supervise the operation and management of other subject, and give the report of the record data regularly. The system can be used to discover the problem in sludge disposal, and also it can give suggestion for the planning and adjust the ability of sludge disposal in a city for long-term.

Abstract: This experiment used dolomite and the pyroligneous liquid in the process of evaporation and carbonization of apple sticks. We used transformation, mixing, evaporation drying and a series of reaction processes to prepare light-colored low-cost calcium acetate magnesium salt (CMA) environment-friendly deicing salt. Also we tested its performance of melting ice and snow. Its best melting temperature is from -6°C to -11°C. Compared with deicing salt containing chloride ions, it has a higher melting efficiency.

Abstract: in order to study the survival time of the water mist, the quality, energy and motion models were established by using mathematical methods, and then the three models were integrated by fourth-order Runge-Kutta method; at last, by analysis of simulation data, the conclusion were obtained that the survival time of the droplet had been related the particle size and ambient temperature, and their running distance had been related to the particle size and initial velocity.

Abstract: Resin was synthesized by microwave irradiation. The effects of cross-linker dose， initiator dose, and dispersant dose , as well as synthesis reaction temperature on the synthesized resin adsorption of oil were investigated. Morphologies and textural properties of the synthesized resins were characterized by using Scanning Electron Microscopy (SEM). The results showed: In comparison with synthesis method of traditional water-bath heating, the use of microwave irradiation can make the synthesis time shorter, and 10% increase in oil capacity than traditional water-bath heating. The resin had release function, so it can be made wettable powder or granules, which provided another alternative to cream formulations new way.
