Accidents of modern chemical industry may not infrequently transform into environmental disaster, causing a series of social and public health issues. Here the labored example as typical fire and explosion accident of chemical product, refers to the ldquo11ldr13rdquo accident taken place in Jilin Chemical Plant, as to give account to possible hazards the measures adopted as emergencies disposal might...
In view of the abnormal phenomenon that a flood peak increased in August 2004 and July 2005 along the lower Yellow River, the experiments of this abnormal phenomenon is studied. It is found that the flood increase was due to the decrease the channel roughness in the propagation of high concentrated flood carrying the extra fine sediment which was discharged from Xiaolangdi reservoir. Experiments with...
The ecological footprint, as an excellent tool, has received much attention as an indicator for sustainable development over the 10 years. Pasture is one important natural resource. How can we calculate the pasture footprint dominant by agriculture and animal husbandry in Northern China. We take different approaches calculation the pasture. First we use the conventional ecological footprint method...
The degradation and rehabilitation of dry valley are increasingly a focus of scientific and applied interest. This paper reviews the general conditions of eco-environmental degradation and puts forward a landscape approach for rehabilitation. Primarily, soil and vegetation degradation is the main cause of the degradation. Systematic analysis and insights into the soil and vegetation degradation phenomena...
Based on a survey of peasants who lived in rural community in Wuhan City Hubei Province in China, this paper examines the peasantspsila desire for social insurance in rural areas using the multinomial logistic model. The study finds that the peasantspsila desire for social insurance in rural areas is remarkably affected by individual and family characteristics, such as age, number of children, and...
A simple new classical growth model is developed to analyze the relationship between economic growth and environmental pollution, which proves the existence of the sustained growth path. This model is then endogenized to study the interaction among environmental pollution, human capital and economic growth in the long run. The similar growth path is shown and potent influences of different variables...
An integrative fuzzy set pair model, established by integrating fuzzy assessment and set pair analysis, was introduced to assess the land ecological security states. The approximate degree of land ecological security to the optimal standard set was calculated to describe the security level by combining multiple indices. The indices and weights were determined by Delphi and fuzzy AHP (Analytic Hierarchy...
Light Detection and Ranging (LIDAR) is a fast method for sampling the earthpsilas surface with a high density and high accuracy point cloud that is used to generate high density and high accuracy Digital Elevation Models (DEMs) and DSMs. In this research we obtained airborne LIDAR elevation data with spatial resolution of 1 m to reveal new details of mountain block morphology and structure to investigate...
A distributed watershed runoff and sediment production model, reflecting the influences of the spatial inhomogeneity of underlying surfaces and human activities on watershed runoff and sediment production, is constructed. It can simulate the spatial and temporal processes of runoff and sediment production under different kinds of land utilization, and provide technological support and scientific basis...
According the research of the arbitrary excavation method for the three dimensional geologic stratum model, we can be used to analyze the inner structure feature effectively in the geological work. This algorithm is based on the three dimensional geological objects represented by TIN structure. And it extracts the two key operating: ldquothe generation of the cross sectionrdquo and ldquothe partition...
The variation of EPC0s of the re-suspended sediments is studied and the relationship between the distribution of phosphorus forms and EPC0s of sediments is investigated. Results of this study show that sediment re-suspension could promote phosphorus migration from overlying water to the sediments. The EPC0 of the re-suspended sediments reduced evidently from 0.069 mgldrL-1 (the initial state) to 0...
Water quality and local illnesses have some relationships which can not be predicted by simple statistical algorithm so one improved A-Priori algorithm is introduced to objectively meet this question. A-Priori algorithm, which can efficiently find useful associational relationships among databases, is one popular algorithm in associational rule mining. Moreover, this paper introduced some useful and...
Hexachlorocyclohexane (HCH) was one of the major organochlorine pesticides (OCPs) in the water and sediments of the Peacock River in Xinjiang, China. Analyzing the water and sediment samples by gas chromatography-electron capture detection (GC-ECD), it showed that all the HCH isomers (alpha-HCH, beta-HCH, gamma-HCH and delta-HCH) could be found in the sediment, and the range was from 0.13 ng/g to...
In the world, China is one of greatest nation that products and expends lots of electrical appliances. Since the year of 2003, China's household appliances have entered the peak of obsolescence, which discards approximately more than 30 million every year. As China basically hasn't constructed regular reverse logistics system of discarded and used household appliances at present, the majority of them...
With the development of production and the social progress, reverse logistics problem becomes more important; In China, along with strengthen of people environmental protection consciousness and can keep on development strategic of thorough public, the recovery of old product also be subjected to extensive concern. On the one hand, society appeals to the appropriate treatment of used product, on the...
Environmental pollution has been a serious threat to all people's living conditions, restricted the ability of continual economic development. How to control the pollution scientifically, efficiently and rapidly has been one of the important topics in the technology research around the world. So, the guiding principles, the organization and the responsibility of the design of environmental pollution...
This paper proposed a data structure to store irregular warehouse layout diagram. A warehouse unit is defined as four kinds, which are storage point, passage, node and block respectively. The shortest distance and route between two storage points can be calculated by virtue of their adjacent nodes. Based on this, a new genetic algorithm is proposed with an assumption that an order-picking operation...
With increasingly intense competition between enterprises, the realization of advanced supply chain management has become an exquisite premise for the survival of firms. Procurement management is an important means to reduce costs and to enhance the competitive advantage. In this paper, the effect of information technology (IT) cost was considered completely, and the coordination mechanism in two-stage...
Analyzing the needs and preferences of customer is an important task of enterprise to carry out Six Sigma management. In this paper, a method which combines design of experiment method and conjoint analysis technology was proposed to get and numerically analyze the preferences of customer in the product design process of enterprise. Finally, the validity of the method was verified through a practical...
Environmental management are collection of environmental standards, green technological innovation related to patent protection system, economic instruments, financial instruments, and other measures to limit damage to the environmental quality of human. This issue Analysis environmental management mechanisms from the economics perspective: Additional new targets affect the uncertainty of environment...
