摘要/Abstract

摘要： 从景观生态的角度,讨论温带亚热带过渡带的历史变迁过程及其对我国农业和技术的发展、转移、交融等方面的影响.历史时期温带亚热带过渡带界限随气候变化南北移动,寒冷期一般南移1～2个纬度,温暖期北移1～2个纬度.过渡带环境条件复杂多样具有较强的敏感性,在我国南北方农业异质交融、农业技术和文化的异质创新等方面起了重要的景观通道和屏障作用.

关键词: 温带-亚热带过渡带, 景观变迁, 农业景观异质性, 景观通道作用

Abstract: The change process of ecotone of temperate and subtropical zone and its effect on development, transformation and permeation of chinese agriculture and techniques were discussed in this paper from the viewpoint of landscape ecology. In historical time, the boundary of the ecotone changed northward and southward as climate changed, which changed southward 1～2 latitude in cold period and northward 1～2 latitude in warm period. The ecotone had an obvious environment diversity and strong sensibility, and played important role as a landscape conduit and barrier in aspects of chinese agricultural heterogeneous permeation and heterogeneity creation of agricultural techniques and cultures.

Key words: Ecotone of temperate and subtropical zone, Landscape change, Agricultural landscape heterogeneity, Landscape conduit
