摘　　要： 土地利用规划生态红线划定工作对于维护基本生态安全、实现土地综合协调利用与保护、保障区域社会经济发展具有重要意义。该文以连云港市为研究对象,根据土地利用规划的基本目标,应用土地利用生态因子耐受度测算了具体生态限制因子的耐受度值,据此划定了土地利用规划生态保护红线。结果表明:连云港研究区土地利用规划生态保护红线区域共计489.67km2,该区域包括了地形地势、地质灾害、生物多样性、水质与水文条件等所有生态限制因子类型。该文研究方法能够充分考虑到区域生态环境对土地开发利用的约束和限制作用,满足土地利用规划生态红线划定的需要,并可为其他城市开展生态红线划定工作提供借鉴。 The outline of Etologitcal Protection Red Line（ EPRL） for land use planning plays an important role in guaranteeing the over-all ec：ologit;al safety,coordinating the relationshipbetwT een land use and protec：tion and supporting the achieveiment of social and ec：onomic development objectives. Taking Lianyungang City as a case study,a methodology based on general objectives of land use planning was proposed to delimit the EPRL for land use planning in Lianyungang City.W’ith the employment of Land Use Ecological Tolerance Index （LETJ）,the LETJ values of individual ecological restriction indicators were calculated and mapped in GIS platform. Then the ectilogical protection red line for Lianyungang City was obtained based on theLETJ value maps. The results indicate that： 1） the area of EPRL in Lianyungang city is determined as 489 67 km2. 2） All the ecological restriction components including terrain,getilogical haz-ards, biodiversity,water quality and hydrological condition are contained in the area of EPRL. 3） this methodology is capable of fully considering the restriction of regional ecological environment on the land use and meeting the requirement of the outline of EPRL in land use planning,which also providing a good reference for the EPRL determination in other areas.
