| 不合理的人类活动导致生态环境日益恶化，而划定生态红线对遏制生态环境退化、加强区域
生态保护和维持经济社会可持续发展有着重要意义。以重庆市江津区为例，借助空间技术方法，选取高程、
坡度、土壤类型、植被覆盖度和水体5 个指标评价区域生态敏感性；并从土地利用的角度出发，将研究区
分为9 类生态系统类型，选取11 个指标衡量区域生态系统服务价值，最后根据生态敏感性结果和生态服务
价值结果共同划定土地生态红线。结果表明，江津区土地生态红线面积为1 091.30 km2，占江津区总面积的
33.9%。土地生态红线的划定可为三峡库区县域生态保护提供一定参考借鉴。 |

| Irrational human activities lead to the deterioration of the ecological environment，and delineation
of ecological redline zones has great significance to curb the degradation of the ecological environment，strengthen
regional ecological protection and maintain the sustainable development of the economy and society. In this paper，
the study was carried out in the Jiangjin district of Chongqing as an example，under the support of spatial technology
method，5 indexes including elevation，slope，soil，vegetation coverage and water were selected to evaluate the
ecological sensitivity，and the study area was divided into 9 types of ecosystem from the perspective of land use，
11 indexes were used to evaluate the value of regional ecosystem services. According to the results of ecological
sensitivity and ecological service value，the land ecological redline of the study area was delineated. The results
showed that land ecological redline area was 1 091.30 km2，accounting for 33.9% of the total area of Jiangjin district.
Delineation of land ecological redline provides a reference for ecological protection in county area. |
