【Abstract】 Huanghe Delta is the youngest land in China. It is formed while a large amount of mud and sand from Huanghe River silt at the entrance to the sea. Since the natural oil was mined in 1960’s, the State has paid much attention on the exploitation of Huanghe Delta. Shandong Provincial Government plans to build Huanghe Delta into an important base of energy, chemical industry, agriculture, animal husbandry and fishery in 15-20 years. But the current situation and the change of land use level in the last 15 years show that there still exists a series of problems, such as irrational land-use structure, a relatively lower ratio of forestry land, garden land and pastureland to the whole land area, non-agriculture construction land area fast increasing, etc. So rational exploitation of Huangtie Delta has a great significance to the regional sustainable development of Shandong Province.更多还原
