生态环境约束下的黄河三角洲资源开发的思路与模式

黄河三角洲拥有十分丰富的土地资源、石油天然气资源、水沙资源与海洋资源。经过近20年来的大规模开发,出现了诸如土壤盐碱化加重、植被生态系统成逆向演化、海岸蚀退、生物多样性受到破坏等生态环境问题。根据实施可持续发展战略的要求,在对以往资源开发“外延式”模式进行反思的基础上,提出了协调好资源开发与生态环境保护的新思路,即:在保护生态环境的前提下,进行资源的适度开发,在资源开发过程中搞好生态环境保护;以建设生态经济区为目标,以资源高效利用为基础,以循环经济和链式经济为特色的区域经济发展新模式。并探讨了水土资源、能源等矿产资源和海洋生物资源可持续开发利用的途径与模式。

New thought and pattern under the eco-environmental restriction in the Yellow River Delta

The Yellow River Delta is a region abundant in land resources,oil,natural gas,water and sand and ocean resources.But because of large scale exploitation in recent 20years,a series of ecologically environmental problems appear,such as soil salinization-alkalization,vegetation system degradation,seacoast eroding,biodiversity destruction.Based on the thought of old"extension exploitation"model and the request of sustainable development,the paper brings forward a new thought in order to harmonize the relationship between the exploitation of resources and ecological protection in the Yellow River Delta.The new thought is that the exploitation should be moderate and the ecologically environmental protection should be the first.The goal is to construct the ecological economic region in the Yellow River Delta.Based on the high effective utility of resources,this region should develop a new pattern.The pattern is characterized by circulation economy and chain economy.And then the paper discusses the main exploitation patterns of natural resources,such as water,land,energy sources and ocean bio-resources in the Yellow River Delta.
