With the population and the economy growing fastly,in our country's East coastal areas the farming resources decline sharply, the land's unreasonable use intensifies, the ecology is unbalanced, the environment is deteriorated, the contradiction between the shortage of resources and the lives of the people's demand enhances day by day , endangering the sustainable development ability of the social economy and ecological environment seriously, the shallow seas and tidelands resources has provided the livelihood broad space for the humanity, it is our mother of wealth. It will become our country's economic new point of growth to develop.The shallow seas and tidelands resources are rich in the Yellow River delta area, moreover the shallow seas and tidelands area increases unceasingly with the river silt to deposit, it has the huge development potentiality. But the ecological environment of the shallow seas and tidelands is frail, its development use must follow the synthesis, three-dimensional, highly effective and continually using principle. To use the protection combined agricultural development, the fish pond-field three-dimensional ecology to use, the farmland ecology network of forest belts construction, the coastal lawn's synthesis improvement, the green environmental product and the marine culture, the ingression against high production technology and patterns and eco-tourism development use.As a coastal shallow seas and tidelands resources leading market, development level is quite low, the contribution is not very symmetric with its resources'total quantity, the development pattern and the leading economy industry doesn't yet form, the development potentiality and the space still very big, the coastal shallow seas and tidelands will be the most resources and advantages to develop Dongying's economy.In the development practice, all levels of the government department and some scholars deepen unceasingly to the research and the exploration, gradually realizing the important meaning to carry out this research, but the shallow seas and tidelands'development makes the positive contribution for the national economy, but also has had some negative benefits inevitably. This article has analyzed the domestic and foreign coastal shallow seas and tidelands development research development briefly, works in the predecessor in the foundation, deepened to the development use fundamental research, and take Dongying as the example, through the analysis, further proposed concrete countermeasure for Dongying's shallow seas and tidelands development, this has the significant theory significance and the practical significance without doubt to the Dongying's economical and social development. The paper divides into the following six parts: The first part first elaborated the selected topic background as well as the domestic and foreign land suitability research development, the shallow seas and tidelands research development, based on this, elaborated the research significance and the research aim and the method, and made the technical route.The second part has outlined the geography survey of Dongying, the development present situation as well as the existence question. First, from the terrain landform, the soil category, the soil salt content, the soil fast-acting phosphorus content, the soil fast-acting potassium content, the soil entire nitrogen content, the paper has summarized the Dongying's shallow seas and tidelands natural environment; From administrative regionalization, population, GDP, average per person, it has summarized the social economy condition. Next, it has analyzed the Dongying's shallow seas and tidelands development present situation, also man-land relationship, the large-scale development and the environment frail question, the existing shallow seas and tidelands use structure and the shallow seas and tidelands suitability symbol, the water resources'insufficiency, the shallow seas and tidelands degree of utilization is low and efficient, all these show the problem to develop the shallow seas and tidelands.The third part is introduce the artificial neural network, first from the concept to the characteristic, some detailed introduction explained that, next it has a very detailed learning process to the BP neural network, finally, in establishing the BP neural network model the question which needs to consider are made a detailed elaboration. The fourth part has made the countermeasures to the Dongying's three countys'and two areas'suitability of the shallow seas and tidelands'development use. First it lists the principle and the basis of suitability evaluation. Next the factor has been carried on the selection and grading. Once more, according to the evaluation factor, it has established the evaluating indicator system. Finally, it carries on the present situation evaluation with the BP neural network method to the Dongying three countys'and two areas'suitability of shallow seas and tidelands'development use.The fifth part, according to the evaluation results and being against some questions which exists in the shallow seas and tidelands'development use in Dongying, it has highlighted several constructive countermeasure for the shallow seas and tidelands'development use.Last part the paper has summarized the full text and proposed the future direction for further deep research to be against the insufficience.
