Abstract
There are conflicts between developer/landowner and citizen about losing woods by housing development plan. These conflicts are caused by the externality of green-spaces like woods in DID. The main problem is the value of green-spaces is apt to be neglected in the market economy. Therefore it is important to internalize the externality of green-spaces value. To solve this problem, this paper firstly surveys the ongoing legal methods of internalization of externality of green-space, and searches the issues of implementation of these methods, and secondly proposes the improving ways, such as publication of green space value, postponement of public expense, and cutting down the cost of landowner. In this proposed ways we expect rational action of landowners, developers and citizens to conserve green spaces.
