【摘要】：针对生态环境严重恶化的矿业棕地,提出生态化建构的矿业棕地公园为修复对策,以保证棕地景观生态安全.矿业棕地公园景观生态安全格局,依MCR模型建构,将矿业棕地公园内的人工自然生态斑块在景观尺度内作为生态安全格局中的"源"整体考虑,即人工自然的源.人工自然斑块源之间进行联结,依据岛屿理论模型,各"源"间的阻力等值线相切形成鞍状.在生态能流扩散过程中,这个鞍状区就成为不同"源"间的"战略点".组分经确定即设计为矿业城市的生态基础设施.通过选取的景观指数评价分析,与传统规划设计模式对比,矿业棕地公园的生态安全格局与国家倡导的矿山公园相比较,景观破碎化程度明显下降、景观分离度显著变小.景观多样性降低、景观优势程度加大、景观的蔓延度增高.
[Abstract]:In view of the serious deterioration of the ecological environment of the mining Brownfield, proposed ecological construction of Mining Park brownfield restoration measures, to ensure the ecological security of brownfield. Mining brownfield park landscape ecological security pattern, according to the MCR model, the artificial ecological park in the mining of brown patch as in the landscape ecological security pattern scale in the "source" of the overall consideration, namely artificial natural source. The connection between the artificial natural patch source, according to the island theory model, contour tangent resistance the "source" is formed between the saddle. In the ecological energy flow in the diffusion process, the saddle area has become different "source" between the "strategic point". Components of ecological infrastructure has been determined that the design for the mining city. Through analysis of landscape index selection, and the traditional planning and design patterns of mining brownfield Park ecological security pattern and national advocacy compared to mine park The degree of landscape fragmentation decreased significantly, the landscape diversity decreased significantly, the landscape diversity decreased, the landscape superiority increased and the landscape spread increased.
