Study on the Relation between Development and Protection of Greenary in Built-up Areas.

我国大城市建成区绿地稀缺问题日益严重，本文通过我国城市规划体系中绿地减少与土地开发的关系来审视这一问题。城市建成区绿化资源匮乏的原因之一是开发许可存在“漏洞”。由于开发许可制度是对开发商施加苛刻条件的工具，开发商理应寻找“漏洞”。为了科普绿色资源的稀缺，保护绿色开放空间，一些大都市地区的地方政府实施了一些制度。这些制度分为四类：1.实施开发后的绿化保护; 2. 3、在允许开发的情况下保护绿色资源。（四）由地方政府与森林所有者签订的森林保护协议。我们研究了这四种类型，并提出了一个新的综合系统，以保护我们的都会区的开放空间。

The Problem about Scarcity of Greenary in Built-up Areas is Getting Worse in Our Metropolitan Areas.We Examine this Problem by Getting Light on the Relation between Decrease of Greenary and Development of Land through City Planning System in our Country. One of Causes of the Scarcity of Greenary in Built-up Areas is "Loopholes" in Development Permission. Since Development Permission System is a Vehicle for Imposing Onerous Conditions on Developers, it Behooves Developers to Find a "Loophhole".To Cope with the Scarcity of Greenary and to Protect Green Open Spaces, Some Local Government in Metroporitan Areas Put Some Systems into Practice. Those Systems on Grouped Four Types as Follows:1. Protection of Greenary after Development is Practiced, 2. Protection of Greenary when Development is Permitted, 3. Protection of Forests for a Fixed Period of Time by Agreement between Local Gorvernment and the Forest Owner, 4. Fund for Protection of Greenary.We Examine those Four Types and Propose a New Comprehensive System to Protect Open Spaces in our Metroporitan Areas.
