城市化进程中上海植被的多样性、空间格局和动态响应(Ⅶ):上海浦东近自然森林十年间的动态变化及模式优化
Diversity, spatial pattern and dynamics of vegetation under urbanization in Shanghai(Ⅶ):Dynamics and a better construction method of the nearnatural forest in Pudong of Shanghai for recent ten years
摘要
Abstract
The near-natural forest was constructed in Pudong New Area of Shanghai in 2000.The study was made by tracking investigation on species composition of communities, plant density, plant height, DBH and soil nutrient. Results showed that: After ten years, forests showed a good growth. Species of plants maintained almost unchanged except for small amount of invasive species. However, due to the lack of shade, the mortality of evergreen tree species such as Castanopsis sclerophylla , Machilus thunbergii etc. Was high at the first stage of construction. While Ligustrum lucidum and Liquidambar formosana showed a rapid growth and low mortality, gradually dominating the upper stratum, indicating deciduous broadleaved species gradually found their feet and showed up a more stable growth, with soil fertility rising more steadily than that in the early planting period. In response to the problems we found above, a planting model, the bi-synusia model of deciduous and evergreen trees of uneven aged, are put forward, which might play a guidance and reference role in building near-natural urban forests.关键词
