对世界地理整(体性)、差(异性)理论的研究

本文主要探讨整差理论的核心内容，指出：自然地理环境的整体性包括内在联系性，空间组合性和动态演变性。差异性可分为基本差异和派生差异。前者包括纬向地带性和非纬向地带性差异。后者包括垂直带性。地带段性和区域性差异。此外，笔者还论述了各地域分异规律之间的朴素关系以及整体性和差异性的等级划分。最后通过案例指出整差理论不仅能指导世界自然地理现象和事物的研究，而且对人文，社会，环境等问题的研究同样具有指导意义。

A theoretical study on convergence and divergence in world geography

The paper has mainly discussed the central content of theory of convergence and divergence, and pointed out that the convergence of natural geographical environment includes the property of internal relations, space combination and dynamic evolution. The divergence is divided into basic difference and derivative difference. The former includes the difference of latitudinal zoning and the difference of non-latitudinal zoning. The latter includes vertical, sectional and regional differences. Besides these, the author has also discussed the interrelations among different laws and grade division of entire property and different property. At the end of paper, the author has pointed out through example studies that the theory not only directs the study on natural geographical phenomena in the world, but also has directive meaning in the studies on problems of humanity, society and environment.
