【正文】 ancing social, economic and ecological benefits. Ecological economic zone is the main mode to realize the goal of sustainable development. Tennessee River Basin Development ExampleTennessee River is located in the southeastern United States, has an earlier regional development history of immigrants, without the ecological consciousness, this region, which is one of the poorest regions in American, since it suffers from deforestation, and flooding. Until the 1930s, Tennessee River valley development on a large scale. Now, Tennessee valley development is believed to be successful case of the renovation and backward area development. Ecological region development philosophyAll of the natural resources in the valley should be unified to coordination development, must not only satisfy the benefits of some departments or social group, but should seek interests of the full advantage of river basin. Ecological industry as a basin of economic growthFor four parts: ecological agriculture, exploitation and utilization of water resources, ecological tourism and forestry industry. To take necessary precautions to reduce the negative effects arising from the ecological area developmentAgricultural expansion and industry of higheffect development can cause a series of problems. Therefore, they use multiple ways to reduce negative effects of developing ecological geological hazards Redevelopment of Germany39。s Ruhr old industrial zoneGermany39。s Ruhr industrial zone is one of Europe39。s biggest industrial economy areas, which went into a decline phase in 1950s and 1960s. Location of regional ecological advantagesThe bination of production and trade, and the bination of science and technology, research and culture can be seen with the advantages and create location advantages. Ecology industrial adjustment processRuhr industrial zone formed two basic industry chains, one is a high technology industry supported with hightechnology, and the other is the project chain supported with industrial heritage tourism resources redevelopment. The expansion of the concept of regional ecological developmentEarly regional development of Ruhr industrial area is developing economic, while ignoring ecology, later they get the motive power of economic development from ecology. That is China, which is seeking to meet both economic and ecological development, should need to examine and learn the subject. 3 The survey of Poyang Lake Ecological Economic Zone Development backgroundPoyang lake ecological zone, covering 30% of Jiangxi land area, carrying the nearly 50% of the population, created 60% of the total economy, has the good development foundation. Strategic vision Basic ideasConstruction of Poyang Lake Ecological Economic Zone must apply to the concept of ecoindustrial economy developing in accordance with the industrial economy ecology, have a good plan for the development of ecological and economic zone, for achieving the organic unity of scientific development and accelerated development. Target locationTo develop a certain scale of ecological economic system, to construct an environmental protection and resource security system, to beauty living environment system, and various ecocultural system, and ecological system of social harmony and stability. Economic planningEcological economic region can be divided into prohibited developing zone, restricted developing zone, optimized developing zone and key developing zone. Analysis of the advantages and disadvantages Rapid economic development, the overall level is lowSince the 21st century, the GDP growth in Jiangxi province is higher than the same level of the whole country and other central provinces. But due to the weak base, Jiangxi economic development level in central region is still on a low level, which is below the national level. Low consumption of resources, and prehensive utilizationJiangxi Province has the lowest level of energy consumption in the central regions, but lower utilization of industrial waste in Jiangxi. Good ecological environment, strong protection abilityJiangxi enjoys an outstanding advantages of ecological environments, wetland and forest coverage rate with high proportion.4 the problem of Poyang Lake Ecological Economic Zone The deteriorating ecological environmentEconomic, social, policy and history, as well as population, economy, resources, all the multipressure which makes Poyang Lake area loaded heavier and worse the environments. Water environment imbalances, land vegetation degenerationIn recent years, the Lake District lakes appeared atrophy, water quality declining. At the same time, the lake district of forest coverage rate is below the average level. Pollution condition aggravated, biodiversity decreasingDue to the development of agricultural production, Poyang lake water pollution has an ascendant trend, some species are disappearing. Regional Economic lack of core Unbalanced development of the first and second industrial development within the ecological economyPoyang lake area is typical of the agricultural economy, agriculture is selfsufficient of natural economy and low degree of industrial and mercial contribution capability is not strong. The low level of ecological and economic openingupAt present, the internal region is relatively low degree of openness。 the economy is relatively closed and has poor absorption capacity of foreign capital, technology, personnel and other scarce resources. Insufficient infrastructureDue to the shortage of funds, the traffic in round region of Poyang Lake is not so clear. Unbalanced regional developmentPoyang lake ecological and economic zone amasses the place of strongest economic strength, and the weakest one, regional disparity is large.5 The analyses based on Poyang Lake Ecological Economic Zone The wrong development concept of Pollution First, Treatment LaterThe philosophy o
