台风“威马逊”干扰对森林生态系统的影响

2014年7月18日第9号超强台风"威马逊"在海南省文昌市翁田镇登陆,中心风力达到60m/s,是1973年以来登陆海南的最强台风。此次台风对区域森林植被具有较强的破坏力,导致树木倒伏、折干和折枝,严重制约了长期以来形成的区域森林景观结构与功能的持续发展。影响该区域森林生态系统抗台风能力的因素有很多,如树种选择、森林结构、栽植方式、管理水平和树木健康状况等。国内外大量研究和台风"威马逊"干扰后调査结果表明:树种选择是影响森林生态系统抗台风能力最直接的因素,是决定沿海地区防护林、城市绿化和新农村森林景观建设可持续发展的最主要环节。该研究将为海南沿海区域森林生态系统灾后植被恢复提供科学技术支撑。

Typhoon ＇rammasun＇ impact on forest ecosystem in hainan

On July 18, 2014, the 9th super strong typhoon ＇rammasun＇ landed in Weng Tian town, Wenchang city, Hainan Province. Its top sustained winds are near 60 meter per second. This is the strongest typhoon landing in Hainan since 1973.This typhoon cause the regional forest vegetation has strong destructive power,trees lodging and fold branches. The typhoon severely restricting the structure and function for sustainable development of regional forest landscape. There are many resistance factors affect the regional forest ecosystem to resist the typhoon.Such as selection of tree species, structure of forest, planting method, management level and health status, etc.Lots of research at home and abroad and rammasun was not the typhoon after situated results show that the selection of tree species is the most direct factors the regional forest ecosystem to resist the typhoon. It is the key link will decide to coast shelter forest, urban greening, and the sustainable development of the new rural construction of forest landscape. It will supports science and technology of vegetation recovery for coastal areas forest ecosystem in Hainan after disaster.
