生态廊道，通过重力模型完成了生态廊道的重要性分级。结果
表明：1)重庆市主城区中耕地与林地面积之和占比达69.86%
且景观破碎化程度较为严重；2)应对耕地和林地斑块进行分级
规划保护，划分耕地与林地的生态控制区；3)重庆市主城区共
计构建出281条廊道，其中林地型廊道28条、耕地型廊道253
条；4)通过识别生态廊道的土地利用类型，根据重要性分级结
果对生态控制区进行调整，最终识别和划定了重庆市耕地控制

| Abstract: |
| Scientifically and rationally building ecological networks
and delineating ecological control zones can effectively enhance urban
resilience and protect biodiversity. This paper takes the metropolitan
area of Chongqing city as the study area, using the morphological
spatial pattern analysis (MSPA) and the landscape index method, the
network elements composition and landscape pattern of cultivated
land, forest land, water and grassland were analyzed. Two types
of important land use types, cultivated land and forest land, were
extracted and classified according to the patch area and importance
index, and those high-grade patches were taken as ecological sources.
Then, the ecological corridors were identified based on the minimum
cumulative resistance (MCR) model, and the importance classification
of the ecological corridors was completed by the gravity model. The
results show that: 1) The sum of the area of cultivated land and forest
land in the study area were 69% and the landscape fragmentation was
obvious; 2) The grading planning and protection of cultivated land
and forest patches should be conducted, and the ecological control of
cultivated land and forest land should be divided; 3) A total number
of 281 corridors were identified in the study area, including 28 foresttype corridors and 253 cultivated land corridors; 4) By identifying
the land use types of ecological corridors, adjusting the ecological
control zones according to the results of importance classification and
improving the planning of ecological corridors are the directions worth
discussing in the ecological planning field. The research results can
provide references and enlightenment for the delineation, adjustment,
and construction of ecological network in the metropolitan area of
Chongqing city. |
