土地是人类社会赖以生存发展的最基本的自然资源,而土地资源是有限的,如何有效利用土地,实现经济效益和社会效益的最大化,已成为一个重要的研究课题。本文基于Logistic曲线模型研究了其发展过程及特点,将土地利用划分为“自然利用期—粗放利用期—集约利用期—过度集约期”4个发展阶段。分析了各阶段体现出来的社会特征,并提出土地集约的重要性。 Land is the most basic natural resource on which human society depends for its existence and development. However, land resources are limited. How to use land effectively to maximize economic and social benefits has become an important research topic. Based on the Logistic curve model, this paper studies the development process and characteristics of land use. It divides the land use into four stages: “natural use period - extensive use period - intensive use period - over intensive period ”. Analyzes the social characteristics reflected in each stage and puts forward the importance of land intensive.
