The paper puts forward automatically generating method for three-dimension virtual model of buoy based on S-57 chart data (AGM for short), and describes extraction and analysis of buoy data from S-57 chart data, automatically generation of three-dimension buoy model and the flashing animation of buoy light quality in detail, and finally gives the experimental data and results. 1 Introduction Buoy is a navigational aid which is set for helping ships to navigate on the specific water area, and also is an important component of the safety of marine traffic and the significant measure of keeping marine transportation fluently.
The development of buoy is of great significance to our country’s water transportation, ocean resource development, offshore fishery, national defense construction and safeguarding national sovereignty.
Whether model is good or not and professional or not, will directly affect the results of running, the fidelity of scene and navigation efficiency.
Such as one kind of light quality of security water buoy is: white, isophase, period of 4s, so we can know the buoy specific flashing rhythm is light 2s and shade 2s in one cycle.

.: • what type of response to the crisis should be chosen,, with which staff representation on what area at what time, • what is the expected workload of emergency responders, • how looks the demand for services in different areas and what is the expected demand, • what level of service should provide fire unit within each rescue area, • comply arrival times of each fire station. [2] Risk assessment A fire risk assessment traditionally consists of an analysis based on six key elements: fire flow (water), probability, consequence, occupancy risk, demand zones, and community profile.
Currently, they are profiled quick and effective technical assistance in emergency situations (accidents, technical interventions, fires and at heights above free depth, causes on the water) in the most countries.

While we shouldn’t deal with sealing pile on the north side of house, and we should force north of the house settle by the heaped method and soil water immersion stress release method, at the same time for building settlement observation.
The scheme of the heaped method and soil water immersion stress release method: Due to the foundation filling are lager compressibility, So, we can force north of the house settle by the heaped method and settlement observation at the same time, If the house north of ground subsidence don’t reached the design requirements, it can use soil water immersion stress release method to consummate the scheme.
The construction principle: The scheme of the heaped method is in the side of the building settlement smaller stack to increase the additional stress of the side, then increasing the foundation settlement, So as to gradually adjust the houses on both sides of the differential settlement, soil water immersion stress release method excavate a horizontal channel and infuse water according to the requirement of the design on side of the smaller settlement, reducing the foundation bearing capacity, result in settlement increase by load pressure, so as to achieve housing rectification requirements.
In addition, Design units should also entrust to have the corresponding qualifications of professional measuring precision levelling and tilt measurements on a regular basis, On the one hand for checking before settlement of two groups of measuring data, On the other hand to have a better idea of lean back of building.

The professional function is mainly composed with manufacturing, high-tech and tourism industries, partly with the municipal public service centers, cultural sub-center, business associate center, high-tech R & D base.
The landscape features of Jiangnan in Changzhou will be extended, water will been taken as the key link, green as oriented, and the city as the project, water green will be dependency, and good urban ecological environment will be built.
An east-west axis named "Long Yuan green axis" which is 1200 meters length and 150 meters wide will be focus planned in order to link up the river water of Zaojiang River and the green of Dinosaur Park.

Since the 1990s, China began to promote the development of sustainable architecture, and puts forward the concept of sustainable construction with Chinese characteristics-“energy and land saving buildings ”, the main content including energy, land, water saving, material saving, emphasis on sustainable development, in order to deal with the contradictions increasingly urgent population, resources, environment and industrialization, urbanization, rapid economic growth.  
In this evaluation, the definition of green building is “the whole building life cycle, to maximize the conservation of resources (energy, land, water saving, material saving), protect environment and reduce pollution, provide health, application and efficient use of space for people, symbiotic harmony with the natural building” [2].
Make full use of the natural landscape and the natural energy, water saving and land saving and material saving, pollution control on site, reduce the influence of the surrounding hydrology, wind power, lighting and ecological diversity, establish people-oriented green building system of biological and non-biological systems.
In respect regional culture environment, construction, under the premise of human relations, integrated rational organization of construction technology, using cross multidisciplinary cooperation, more professional, the curing and application of methods and means of implementation, coordination system combined with indoor and outdoor environment building body, achieve the pleasant, comfortable target.

They play a certain role in increasing the income of the farmers, but the majority of them also bring water pollution, solid pollution, air pollution, noise pollution, radioactive pollution and soil pollution.
In the history of China, the water way is an important mode of transportation.
Water pipeline, road lamp, waste disposal facilities and fire facilities, all these should be fixed based on keeping environment of ancient town.
Increasing literacy, professional training and health education can constitute important steps to improve autonomy and self-capacity of ethnic groups in order to break the poverty circle.
