The paper analyzes the main problems related to resource and env ir onment in the ar-eas of The Bohai Sea Rimland,Yangtze River Delta and Pearl R iver Delta through a com parative method.The regional differentiation character s that the water resource shortage is getting more se-rious from south to north ,the farm resource waste is getting worse from north to south and envi-ronment al pollution is increasing together with the development of regional economy i n the east-ern coastal areas in China are put fo...

采用比较研究方法，分析了环渤海地区、长江三角洲地区和珠江三角洲地区的主要资源环境问题，提出了我国东部沿海地区水资源短缺由南向北明显加剧、耕地浪费状况由北向南趋于恶化、环境污染程度与经济发展水平同步增长的区域分异特征，并对产业结构演进，特别是工业化过程中地区经济发展与资源环境的相互关系进行了探讨，归纳并修正了二者之间互动模式，提出了建立资源友好型的产业体系、加强资源环境管理规制等优化对策。

The deltas differ from typical deltaic model.Deltaic front subaqueous distributary channel sand bodies and deltaic plain distributary channel sand bodies are the skeleton sand bodies of meandering stream-shallow sea delta and braided streain-shallow lake delta respectively but not tranditional deltaic front river mouth sand bars.

这两类三角洲与经典的三角洲模式不同的是，三角洲前缘水下分流河道砂体和三角洲平原分流河道砂体分别构成了曲流河浅水海相三角洲和网状河浅水湖泊三角洲的骨架砂体，而不是传统认为的三角洲前缘河口砂坝。

Biyang fault-depression experience three evolutional phase: Mesozoic pull apart, Paleogene rift. Neogene downwarp basins. So it has in turn three basin-fill sequences and responding tectonic sequences, which were specified by regional unconformity; their general sedimentary style respectively is assemblage of fluvial fan～flood lake depositional system, fluvial fan ～ fan delta ～ lacustrine ～ delta depositional system. and fluvial plain ～ sand mudstone flat depositional system.

泌阳断陷历经中生代小型拉分盆地、早第三纪裂陷盆地和晚第三纪坳陷盆地等三个盆地原型的演化、叠合过程，形成了三个盆地充填序列及其所对应的三个构造层序，其界面皆为区域性构造不整合面；沉积总体样式分别为冲积扇～洪水-漫湖沉积体系组合、冲积扇～扇三角洲～湖泊～三角洲沉积体系组合、冲积平原～砂-泥坪～滨浅湖沉积体系组合。

Thus, based on analysis and situsurvey in Zhoushan area, some proposals are put forward on utilization of marine resources in Zhoushan Archipelago:(1) The deep shoreline resources can be used to build international deepwater port for transferring raw materials such as metal ore, coal, and crude oil. Furthermore, they can be also built up as a process industry base relying on harbor for staple goods and a standby deepwater port for transporting goods of the Yangtze River Delta outward.(2) There is a great potential on the development of deepwater aquaculture and offshore fishing.(3) It is an appealing resort for marine tourism especially in holiday relaxation which supplies the gap of tourism in the Yangtze River Delta.

基于对舟山群岛的实地调查研究，指出舟山群岛海洋环境资源在长江三角洲中的独特性，并提出舟山群岛海洋资源利用的主要方向：①发展国际性深水中转港，大宗货物的临港加工业基地及长江三角洲货物外运的备选深水港基地；②改进传统渔业，着重发展深水养殖业及远洋渔业等新型渔业；③开辟海岛休闲度假旅游，填补长江三角洲缺乏海岛旅游的缺项。

This thesis will be expanded from two aspects: first, delta-sequence obtained by cubic spline interpolation cardinal function showed the properties of symmetry, Riesz basis and interpolation. Non linear convection diffusion equation (Burgers′equation) was used as an example. Then we modified this delta-sequence to improve the attenuation, the same example was used in numerical application.

在小波方法与PDE算法相结合方面，本文主要从两方面入手：首先是以样条插值基函数为基础构造δ-序列核，以非线性对流扩散方程为例给出了一种数值算法；进而对三次样条插值基函数进行改进，构造新的具有更快衰减性质的δ-序列核，同样以非线性对流扩散方程为例验证了新函数在数值求解中的有效性。
