城镇密集区山地公园绿地的植被恢复探讨

在分析城镇密集区山地公园绿地的特点及问题的基础上,阐述了植被恢复的意义。以内江市塔山公园为例,调查了该公园的生态环境概况和植被情况,结果表明:内江市塔山公园地形陡峭,生态环境脆弱,坡地植被较少,岩石裸露率高,群落结构简单。针对调查结果,提出主要采用自然恢复、人工恢复两种方法进行植被恢复。其中,着重从坡度划分的角度,探索了如何利用植物筛选、群落配置技术对山地公园不同坡度类型的绿地进行植被恢复。

Research on Vegetation Recovery of Mountainous Parks in City-and-Town Concentration Areas

Based on the analysis of features and problems of green lands in mountainous parks in towns concentration areas,the paper has illustrated the significance for vegetations’ recovery.By taking Tashan Park in Neijiang City for example,it has investigated the eco-environment and vegetations of this park.The results show that its terrain is precipitous,eco-environment is weak,slope vegetation is less,rocks’ exposing rate is high and community structure is simple.In view of the survey results,it has proposed two methods for vegetation recovery that are natural recovery and artificial recovery.In particular,it has explored how to conduct vegetation recovery on green lands of different gradients of slopes by using plants’ selection and community disposition.
