植被—气候分类指标及其应用

１引言植被是陆地生态系统的主体，是陆地景观中最显著的和最具特色的组成部分，也是生态系统、气候与土壤亚系统相互联系的枢纽。一般而言，在较大范围或洲际尺度上，气候是决定陆地植被类型及其分布的最主要因素，植被则是地球气候最鲜明的反映和标志［１］，植被与气候...

Indexes of Vegetation-Climate Classificateon and its Applications.

Vegetation-climate interaction is an old topic,but it becomes the most fundamental and vigorous researches for global change study at present.The principles,metyods,applications,advantages and weakness of the classification indexes of single factor or multi-factors assembled simply such as Koppen,Box indexes,and the indexes synthetically based on the concept of potential evapotranspiration such as Penman, Thornthwaite,Holdridge,Budyko,Kira indexes etc.,were discussed, The multitudinous schemes of vegetation-climate classification based upon the indexes in cluding Holdridge,Uvardy,Matthews,Olson,Bailey,Woodward, Prentice and Box schemes werealso discussed. These indexes and programs of vegetation-climate classification can establish some good bases for the present vegetation-climate interaction studies,global change and its impact on terrestrial ecosystems,and prediction of potential vegetation under increasing atmospheric CO 2.
