Abstract:This paper analyses ecological environment in the Yellow River Delta by applying ecotone theory and puts forward a formula of environment potential index(E) to measure environmental quality. Then, the formula is used to do evaluation and pre-warning of present ecological environment in the Yellow River Delta.After calculating E Values of Dongying's west City, East City and 92 rural and town regions, The evaluation. result shows that the general environmental quality is good at present and there is still more potential environmental capacity in the Yellow River Delta, which is favourable for development and construction on a large scale. But the situation of environmental quality is not balance. Some pre-warning should be given to six places which account for 6. 4% of the area and mainly are city, oil-field concentrating districts, county towns beside the Yellow River and the district of the Yellow River mouth.This paper also puts forward environment measures. The Yellow River Delta region is ecotone and more backward, and it is faced with dual tasks of developing economy and protecting environment. Only make the economic-social-ecological benifits integration, can the region gain sustainable development.
Keywords:the Yellow River Delta  ecotone  evaluation  per-warn  environment potential index (E)
