the new network on September 18 in Zhejiang Xinhua Shanghai's forest coverage rate from 3% in the early 90s, to the current 10%. However, in Shanghai What factors influence biodiversity, urban water, earth, air,mbt best price, hygiene environment in the event of the four ecological indicators and what changes, but still can not find specific data. In this regard, long-term ecological research in forest ecosystems Tiantong National Field Station Station


Professor Wang,Nike Griffey, the Shanghai forest pests and diseases present,nike kids, only the observation point, but its ecological effects and the growth of green communities situation, but no detailed data. If the existing diversity in Shanghai to observe the evaluation of artificial models, on the Expo site will provide useful experience in green building. In fact, many cities in developed countries have built a forest stations, the UK's oldest observatory in Lausanne, more than 100 years of history.
Professor Wang revealed green best results must be mixed selective tree breeding,Nike Ken Griffey Shoes, tree, shrub and herb layer of the organic mix. The best state is in full accordance with the natural environment to configure the mature natural community, which must be evergreen and deciduous tree species, mixed species mimic natural communities, through natural selection, survival of the fittest choice will ultimately lead to near natural forests. The early plantation forests are nurseries,coach eyeglasses frames, the lower shrubs, herbs are not configured, a simple community structure, species diversity is low, is likely to cause serious diseases and pests, but will also affect the function of greening and environmental benefits of carbon sequestration to play. And how to reasonably and effectively improve the greening effect, you need to have long-term observational data as a basis.
