云南农林螨地理区划研究(二) 云南省农林螨类垂直地理区划

Research on the Geographical Distribution of Agricultural-foresty Acarus of Yunnan Province(2) The Altitudial Figure of Geogrphical Distribution of Agricultural-foresty Acarus

云南省农林螨种类丰富 ,有 15科 36属 130种 ,其中捕食螨 9科 13属 5 8种 ,分布广 ,从海拔 32 0～ 32 5 0m地区都有分布。根据云南省农林螨种类及其垂直地理带分布特点 ,将云南省农林螨的地理分布从从垂直方向分为垂直高寒带、垂直中暖带和垂直低热带 3个层次 ,代表不同海拔、气候、耕作制度和螨类危害、捕食特点等。种类组成的区域特征 ,表现在各区域间环境条件的差异 ;该研究结果为编写云南省农林螨类完整的地理区划和制定农林螨类的综合治理及控制措施提供了理论依据 ,也将更有利于害螨的有效防治和捕食螨的利用等 。

There are 15 families,36 genura and 130 species of Agricultural foresty acarus in Yunnan province,among of them there are 8 families,13 genura and 58 species of predatory acarus.Accoring to the species and the geographical distribution of the Agricultural foresty acarus of Yunnan province,as for the altitudial distribution,the Agricultural Foresty acarus in Yunnan province includes 3 strata:(1)Vertical Frigid Stratum;(2)Vertical Genial Stratum;(3)Vertical Torrid Stratum.The Regions and Strata not only represent the different elevation,climate,the system of cultivation and the characteristics of the Agricultural acarid's distributional region but also represent many local acarus to show the character of its region.
