石灰岩山地人工造林和封山育林促进阔叶树天然更新技术

Techniques Afforestation and Hill-closure Conservation-promoted Natural Regeneration of Broadleaved Forest in Jianghuai Limestone Hills

石灰岩为江淮丘陵地区主要的岩石种类,具有山体连绵起伏、山势陡峭、岩裸比例高、自然植被稀少和生态退化严重等突出特点。本文尝试通过侧柏人工造林和封禁保护相结合的方式,探索退化石灰岩山地自然生态修复的可行性,为石质荒山生态修复提供参考。

Limestone is a main type of rock in Jianghuai Hilly Region with continuous rolling and steep hills,high-proportioned bare rock,sparse natural vegetation and severely degraded eco-environment.In this paper,an attempt was made to explore the feasibility of ecological restoration of degraded limestone hills by combining afforestation of Platycladus orientalis with hill-closure conservation,so as to provide reference for ecological restoration of barren limestone hills.
