摘要
基于景观生态学原理对大姚县城近、中、远期的的公园绿地、生产绿地、防护绿地、附属绿地及其他绿地进行规划,并用景观生态学的多样性指数、优势度指数、均匀度指数和斑块破碎度、斑块密度、廊道密度6个指标对该绿地系统规划的景观格局进行评价.结果表明,到规划期末,县城绿地系统景观异质性增大,优势度降低,均匀度增加,破碎度提高,斑块密度降低,廊道密度上升,景观格局趋于合理.
The paper makes short, middle, and long term plans respectively on Dayao county＇ s public park, nursery, green buffer zone, attached green space, other green space with the ideas of ecology theory and people-oriented theory, and uses 6 ecological indexes to evaluate the patterns of the Green Space System Planning, including diversity index, advantage index, average index, patch fragmentation, patch density and line corridor density. The results show that by the end of the planning, the differentiation of green system landscape will increase with low dominance but high evenness, high fragmentation and corridor density and low patch density. In addition, the landscape pattern will tend to be reasonable.
