摘　要：

“灰色用地”是一种超前考虑和主动实行“退二进三” 的弹性用地。本文首先剖析了国内开发区土地低效利用的深层原因，主要包括缺乏有效科学的规划引导，以及土地出让年限过长等。其次，通过借鉴鲁尔工业区的棕地再开发和布林德利地区的“混合使用”理念，明确开发区产业发展的基本进程。继而研究了适合我国国情的主动考虑工业发展过程的“灰色用地”规划模式，并提出了“灰色用地”的一般概念、规划选区和过程、运营机制等，最后通过“灰色用地”在镇江开发区的规划布局探索，初次提出短期型产业区和长期型产业区，提高“灰色用地”在开发区规划中的操作性，从而为我国开发区土地集约发展提供了一种新思路。

Abstract：

“Grey Land” is an elastic land use of advanced consideration and active implementation for the “transformation from secondary industry to tertiary sector”. The article analyzes the underlying causes of low-efficient land use in development zone which includes lack of scientific planning and the over-length of land leasing，then clarifies the process of development zone by referring to the cases of Ruhr Industrial Region and Brindleyplace of Birmingham. It continuously discusses “Grey Land” planning method which fits the circumstances of China and puts forward its concept and operating mechanism. At last，by the case study of Zhenjiang Development Zone，the paper brings up the short-term and long-term Industrial area for the first time and provides a new idea to promote intensive land use of development zones in China.
