云南农林螨地理区划研究 (一)云南省农林螨类平面地理区划

 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58种,分布广,从海拔320～3 250 m地区都有分布。根据云南省农林螨种类及其平面地理带分布特点,将云南省农林螨的地理分布从平面分为7个区,代表不同海拔、气候、耕作制度和螨类为害、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,为制定农林螨类的综合治理和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,同时也有利于可持续农业发展的总体规划与实施。

Research on the Geographical Distribution of Agricultural-Foresty Acarus of Yunnan Province I The Plane Figure of Geographical Distribution of Agricultural-Foresty Acarus

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 acarus of Yunnan province,there are 7 regions on the plane figure,they are: 1. Central Yunnan Plateau Region; 2. West Yunnan Basin Region; 3. Southeast Yunnan Karst Region; 4. Southwest Yunnan Wide Va1ley Region; 5. Southern Border Region; 6. Northeast Yunnan mountainous Plateau Region;7. Northwest Yunnan Plateau Valley Region. 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.
