This article establishes a set of indicators and standards for landscape ecological sensitivity analysis of site resources by using the theories and approaches of landscape ecology. It uses landscape diversity index (H), evenness (E), natural degree (N), contrast degree (C) to study spatial structure and landscape heterogeneity of site resources and thus provides a qualitative-quantitative evaluation method for land planning and management of small, medium scale areas. The analysis of Yantian District, Shenzhen of China showed that Wutong Mountain belonged to high landscape ecological sensitivity area, Sanzhoutian Reservoir and Shangping Reservoir were medium landscape sensitivity and high ecological sensitivity area; Dameisha and Xiaomeisha belonged to medium sensitivity area caused by the decline of natural ecological areas. Shatoujiao, Yantian Pier belonged to low sensitivity area but urban landscape ecological development had reshaped and influenced their landscape ecological roles in a great extent. Suggestions on planning, protection goals and development intensity of each site or district were raised.
本文运用景观生态学的理论和方法,建立了一套场地资源景观生态敏感性分析的指标和标准。利用景观多样性指数(H)、均匀度(E)、自然度(N)、对比度(C)研究场地资源的空间结构和景观异质性,从而为中小尺度区域的土地规划和管理提供了一种定性定量的评价方法。对中国深圳盐田区的分析表明,梧桐山属于景观生态高敏感区,三洲田水库和上坪水库为中等景观敏感度和高生态敏感度区域;大梅沙和小梅沙因自然生态区域的下降属于中等敏感区。沙头角、盐田港属于低敏感区,但城市景观生态发展在很大程度上重塑并影响了它们的景观生态作用。针对各场地或区域提出了规划、保护目标和开发强度的建议。
