其他摘要：In order to study the relationship between urban and rural land expansion and wetland utilization in the Yellow River Delta and find out the methods to promote the harmonious development of regional land use and ecological environment, Dongying and Binzhou, the core cities of the Yellow River Delta, are taken as the study areas. The expansion intensity index, landscape index and center of gravity transfer index are used to analyze the relationship between urban and rural land expansion and wetland utilization in the study areas 1973-1980, 1980-1990, 1990-2000, 2000-2010 and 2010-2018 five periods of two types of land use indicators for analysis. The results show that the Yellow River Delta is still in a slow development in these five periods, and the urban and rural land expansion rate and wetland change rate vary greatly in different stages; the landscape pattern of the Yellow River Delta is becoming more reasonable; the urban morphology is becoming more compact, and the urban structure is more standard; the urban and rural land use as a whole, the center of gravity is gradually shifting to the northeast, while the wetland as a whole, the center of gravity is shifting The points gather together, and the migration direction is chaotic. The development of urban and rural land is becoming more and more mature, while the development of wetland is relatively unstable. The phenomenon of alternating expansion strength of urban and rural land and wetland in all directions indirectly reflects the contradiction between land use and ecological environment to a certain extent, but the overall direction is still consistent. The research results can provide scientific basis for the urban management of Dongying and Binzhou, and also provide methods and references for the research of the same type of cities.
