This paper also brings forward the strategic target of planning and designing the green system in this region to provide reference and guidance for planning work. Based on GIS, this paper analyzes landscape spatial pattern, dynamic pattern and landscape functional division. And it holds out the planning project to major the structure of green system in the research zone. And that is the core content in this research. There is peculiar sense to represent and extend the psammophyte garden in justifying the agriculture framework in the research zone. So this paper takes the psammophyte garden as a concrete unit to proceed landscape eco-designing.

在对研究区的自然、社会环境及其景观生态基本特征等深入分析的基础上，提出了该地区绿地系统景观生态规划与设计的目标，为规划工作提供依据与指导；在地理信息系统支持下，进行景观生态分类与制图、景观空间格局及其动态分析以及景观功能分区，在此基础上提出研究区绿地系统结构优化的规划方案，这是本研究的核心内容；由于沙生植物园区的示范推广对研究区的农业结构调整具有特殊的意义，因此，本文以白埕村沙生植物园区作为具体单元，进行景观生态设计。

This thematic GIS privedes various landslide、debris-flow、rainfall and emergency materials information query interface. To give a dynmatic, vusual view of the landslide, debris-flow, and entir expressway and its adjacent terrain, the function of 3D visualization models. The method for computing the stability properties of landslide and debris-flow in this system, as well as providing decision support to the emergency resue.

With the increasing transportation of liquid chemicals in bulk by ships, the risk of the chemicals spill is getting higher and higher. So the reasonable numerical modeling of the spilled chemicals at sea is a key technique for the risk assessment and contingency decision-making. The sinkable chemicals spilled at sea always ended in sediment, so the design of decision-making support system for sinkable chemicals spilled shipboard have academic and applied sense.Based on the analysis for the environmental harm caused by the transportation shipboard of chemicals and research on related ordain in the international common and intestine law , the paper analysis the impelling need of establishing related respond system for contaminative accident.
