- 摘要:
- 树种气候区划对地区园林树种引种栽培和树种的迁地保护具有重要参考价值。该研究通过对内蒙古地区119个气象站点近30年来温暖指数和干湿度指数进行分析，采用半峰法并结合其与经纬度、海拔的回归方程得出旱柳气候区划图。结果表明：大兴安岭岭上、阴山山脉及狼山等高海拔地区为旱柳热量不足区；大兴安岭岭东南、中西部大部分地区为热量适宜区；湿度偏高区仅存在于大兴安岭北部，湿度不足区主要分布在西部荒漠化草原和荒漠区；水热适宜区主要分布在大兴安岭东南地区；东部区主要制约因素为热量，西部区则为水分条件。综合区划结果表明，气候适宜区划是树种存在存活的基础，而下垫面树种分布则受到地理、人为、社会等诸多因素的影响，树种气候区划是植被区划的基础，其结果可为地区园林树种选择及其相应的养护管理措施提供参考依据。
- Abstract:
- The climatic division of forest has very important reference values to the introduction and cultivation of the garden species,and to the migration of forest protection.The study used 119 meteorological stations′ data（1984—2013）in Inner Mongolia to calculate the site warmth index and humidity/aridity index,by using the half peak width method and the regression equation of warmth index and humidity/aridity index with the longitude and latitude and altitude,the temperature and humidity and comprehensive zoning map of Salix matsudana Koidz.was concluded.The results showed that insufficient heat areas of Salix matsudana Koidz.mainly distribute in the higher altitude areas of the ridge of Greater Khingan mountains,Yinshan Mountains and Langshan Mountains;the heat suitable areas mainly distribute in southeast of Greater Khingan Mountains，midwest most areas of Inner Mongolia.High humidity area only exists in the north of Greater Khingan Mountains;insufficient humidity areas mainly distribute in the western desert and desert steppe.Heat and humidity suitable regions mainly distribute in the southeast of Greater Khingan mountains,the distritution of tree species in the eastern area of Inner Mongolia were mainly restricted by heat condition,and that western area were restricted by humidity.Climatic regionalization result was the basis of the survival tree,the tree species distribution was affected by geography,human and social factors and so on.The climatic regionalization of tree species was the basis of vegetation regionalization,the results could give reference for tree planting regionalization and management measures.
