녹지자연도와 경사도를 이용한 택지개발 보전지역설정에 관한 연구 : 청주 율량2지구 택지개발지역을 대상으로

택지개발지역의 녹지와 경사도를 고려해 보전지역 설정을 연구했다.

The development of science technology and medicine in modern society has lengthened human life, generating problems with rapid population increase, environmental destruction, urbanization, and industralization. To solve these problems, urban policy in the 21st century is progressing with a method that first establishes an environmental plan and later makes a development plan under a new paradigm "environmentally healthy and sustainable development," which pursues environmental preservation and effective development at the same time. Since the 1960s, our nation has achieved rapid industralization and urbanization, following a policy that puts priority in economic development.

The development demanded formation of large-scale industrial and housing sites including infrastructures such as roads and harbors. These large-scale developments have inevitably induced environmental destruction. As concepts such as integration of environment and economy and sustainable development in 1992 Rio summit were introduced, environment-friendly development has been pursued. On the contrary, development causing large environmental damages has been reduced.

When sites for land development or industry development is designated, a prior environmental investigation or an environmental impact assessment should be conducted However, conservation areas are not being designated and managed in agreement despite conduction of the above investigation and assessment. There might be many reasons. However, it is judged that an inadequate analysis system for assessment items connected with preservation areas is a critical cause.

Thus, in order to plan a land development site that is environmentally healthy and sustainable, this research looks at how a preservation area is selected under the environmental impact assessment system and prior environment investigation system, and deduces slope and green naturality degree items, Then, it tries to prepare a method to select conservation areas in land development sites by overlapping a slope and a green naturality degree without individual assessment of them. By applying the overlapping system of a slope and a green naturality degree in the Yullang 2 housing development sites, conservation areas were increased by 2 more subareas and 16,202㎡
