采矿废弃地植被恢复与可持续景观营造研究——以湖南冷水江锑矿区为例

Study on the Vegetation Restoration and Create a Sustainable Landscape—— As an Example Hunan Lengshuijiang Antimony Mine

锑矿废弃地主要为重金属污染林地,植被恢复的核心问题在于解决植物生长的生境,其中最关键的是改良土壤环境。基于土壤环境改良的前提下,充分考虑植物景观的营造手法,结合生态学要求构建近自然群落,增强物种多样性,通过生态学、景观设计学,使原有破碎化景观"变废为宝"。通过对国内外采矿废弃地复垦技术的研究以及冷水江当地乡土植被群落调查及锑矿区的现场踏勘研究,提出了适用于类似采矿废弃地植被恢复的修复手段,并结合植物造景原理提出可持续景观营造模式。

Antimony are mainly heavy metal pollution in abandoned woodland, vegetation restoration is to address the core issue of the habitat environment for plant growth lies in one of the most improved soil environment. Based on the premise of improved soil environment, give full consideration to the way in creating the landscape of plants, combined with ecological requirements to build near-natural communities, enhance species diversity, through ecology and landscape architecture, so that the original fragmented landscapes, ＂turning waste into treasure.＂ In this paper, mining land reclamation of the domestic and international technology research, as well as local native vegetation communities Lengshuijiang investigation and antimony mine site reconnaissance study, was proposed for a similar vegetation to restore abandoned mine restoration tools, combined with plant landscaping principles proposed to create a model for sustainable landscapes.
