亚热带地区不同垂直气候带的农业生态经济效益分析——以四川省宁南县为例

ANALYSISJ OF THE AGRO-ECONOMIC EPFECTS.IOF VARIOUS VERTICAL CLIMATIC ZONES IN SUBTROPIC AREAS-CASE STUDY IN NING NAN COUNTY OF SICHUAN PROVINCE

此调查选择在垂直气候带分区较明显的四川省宁南县进行,本文通过对不同垂直气候带典型户的调查,运用能反映经济效益、生态效益及社会效益的一些具体指标,结合当地的农业生产结构,对三个气候带的农业生态经济效益进行了分析比较,最后得出南亚热带的效益最好,中亚热带次之,而北亚热带及暧温带最差。最后,根据不同气候带的具体特点,指出了各自提高系统整体效益的一些途径及措施。

Soms typical farmer haussholds of different climate zones were investigated. Their agro-economic effects were analysed and compared with several indexes reflecting economic, ecological and social effects and integrated with the agricultural prodution structure. The conclusions was that the integrated effects of Southern Subtropical Zone was the best, Middle Subtropical Zone the second and Northern Subtropical Zone and warm Temperate Zone were the worst. Some methods or ways for improving the integrated effects of each climate zone have been suggested according to the special characteristics of each one.
