An Analytic Model Proposal for Ecological Planning � �merli Watershed Case

The idea of disscussing natural values within the context of conservation � use balance (in other words sustainability of natural resources), has been taking place in planning agenda particularly starting from the last quarter of the former century. This consciousness, which is based on a practical necessity (solution proposals for the wide range environmental problems), directed planning discipline to a well recognition of the natural sciences and particularly ecology. This new orientation, caused some new research fields, like a planning approach that aims to internalize the natural values and some tools serving this aim, to develop. Today, the approach known as �Ecological Planning� is a product of the above-mentioned attempts.
This article, is presenting the findings of a settlement suitability evaluation, which was developed within the framework of Ecological Planning Approach and carried out with the help of a three stepped analytic model proposal, for �merli Watershed. These three steps could be summarized as follows; an analytic study to state the natural sensitivities of the study area, determination of factors, factor scores and weights (with the help of Analytic Hierarchy Process) for evaluation and �Suitability Analysis�. The watershed is disscussed with its relatively virgin structure in 1970�s (using the data of 1970�s) and the findings of suitability evaluation is compared with today�s landuse pattern also interpreting actual environmental problems within their cause and effect relations. In other words, the effects of a development approach which is not considering the before-mentioned consciousness is evaluated.

Keywords: Ecological Planning, Suitability Analysis, Analytic Hierarchy Process.

Do�al de�erleri bir koruma kullanma dengesi i�erisinde ele almak fikri, bir di�er deyi�le do�al kaynaklar�n s�rd�r�lebilirli�i, planlama disiplininde a��rl�kl� olarak ge�en y�zy�l�n son �eyre�inden ba�layarak kendisine yer bulmu�tur. Pratik bir gereksinmeden (ya�anan geni� �apl� �evre sorunlar�na ��züm aray��) kaynaklanan bu bilin�, planlamay�, do�a bilimlerini �zellikle de ekolojiyi daha iyi tan�maya y�neltmi�tir. Bu y�neli� do�al de�erleri daha iyi i�selle�tiren bir planlama anlay��n�n ve bu amaca y�nelik olarak kullan�labilecek ara� aray��lar�n�n da �nemli birer �al��ma sahas� olarak ortaya ��kmas�na neden olmu�tur. Günümüzde �Ekolojik Planlama� olarak bilinen yakla��m yukar�da s�z� edilen aray��lar�n �r�n�d�r.
Bu yaz�, Ekolojik Planlama yakla��m� �er�evesinde geli�tirilen ve �� temel ad�m� i�eren analitik bir model �nerisi ��nda �merli ��me Suyu Havzas��n�n yerle�meye uygunluk de�erlendirmesi sonucunda ula��lan bulgular� sunmaktad�r. Bu �� ad�m; �al��ma alan�n�n do�al de�erlerinin hassasiyetlerini saptamaya y�nelik analitik bir �al��ma, de�erlendirmede ele al�nan fakt�rlerin, fakt�r puanlar�n�n ve a��rl�klar�n�n (Analitik Hiyerar�i Süreci yard�m� ile) tespiti ve �Uygunluk Analizi� �eklinde s�ralanabilir. Havza 1970 y�l�ndaki g�rece bakir yap�s� ile ele al�nmakta (dolay�s�yla 1970 y�l�n�n analitik verileri kullan�lmakta) ve yerle�meye uygunluk y�n�ndeki bulgular g�n�m�zdeki geli�me deseni ile kar��la�t�r�larak ya�anan �evre sorunlar� neden-sonu� ili�kisi �er�evesinde yorumlanmaktad�r. Di�er bir deyi�le bahsi ge�en bilincin �r�n� olmayan bir geli�me anlay��n�n sonu�lar� bu ba�lamda tart��lmaktad�r.

Anahtar Kelimeler: Ekolojik Planlama, Uygunluk Analizi, Analitik Hiyerar�i S�reci.
