چکیده مقاله :
زمینه و هدف: رشد گسترده افقی شهرها دارای پیامدهای زیستمحیطی است، این فرآیند منجر به تخریب منظر و باغها حاشیه شهرها میگردد. باغها سرابقنبر در جنوب شهر کرمانشاه نیز به دلیل رشد گسترده شهری در معرض تخریب گستردهای قرار دارد.روش بررسی: با استفاده از سنجههای اکولوژی سیمایسرزمین تحولات محدوده مورد بررسی قرار گرفته است. در مرحله بعد براساس برداشت میدانی انواع لکهها و کریدورها مشخص شده است.یافتهها: با توجه به کارکرد این فضاها از لحاظ عملکرد اکولوژیک، عناصر ساختاری محدوده در چهار گروه از راهبردهای حمایتی، تدافعی، تهاجمی و فرصتطلبانه طبقهبندی شدهاند. این طبقات شامل لکهها و کریدورهای طبیعی، اختلالی، مکان و نحوهی قرارگیری آنها بر روی بستر سرزمین میباشد. با درنظر گرفتن اهداف طراحی و این طبقات، طرح راهبردی محدود ارائه شد.بحث و نتیجهگیری: گسترش بستر شهر منجر به ایجاد لکههای اختلالی در سطح محدوده شده و از سوی دیگر لکههای طبیعی گرایش به خردشدن پیدا کردهاند. کریدورهای طبیعی با چالشهای جدی مواجهاند. در حالی که گسترش کریدورهای اختلالی منجر به تغییر در ساختار سیمایسرزمین شده و گسست اکولوژیک را تشدید کرده است. تداوم این روند منجر به نابودی این اراضی خواهد شد و تبعات بسیاری را به دنبال خواهد داشت. طراحی محیطی متناسب میتواند چارچوب مناسبی را با استفاده از مبانی پایه اکولوژی سیمایسرزمین فراهم ساخته و با تعریف کارکردهای متناسب نیاز شهری، این عرصههای طبیعی را حفاظت نماید.
چکیده انگلیسی:
Background and Objective: Sprawl growth of the cities has different environmental impacts. This process leads to destruction of suburban agricultural land and marginal orchards. The devastation of suburb area not only influenced the area, but also it has different impacts on whole city. Sarab Qanbar gardens which located in the southern city of Kermanshah, is largely degraded as a result of urban Sprawl growth. While area protection is compulsory necessity due to the ecological services which provided by this area.Method: Landscape ecology framework were used to develop the area in order to achieve the mentioned goal. Therefore, first the appropriate landscape metrics were used. In the next stage, patches and corridors have been identified and analyzed based on field surveys. Ecological redesign was the final stage.Findings: The strategic design plan of the area was designed, which has been done based on strategic planning. Strategies were classified in four groups of protective, defensive, offensive and opportunistic. Each class determined based on patch and corridors characteristics and their interaction with context. Finally, actions and strategic plan were purposed protection and development of the area.Discussion and conclusion: The expansion of the city has led to the creation of disturbance patches in the region, On the other hand, natural patches tend to be crushed, Natural corridors face serious challenges. While the spread of disturbing corridors leads to changes in the structure of the landscape and the ecological fracture has intensified. The continuation of this process will lead to the destruction of these lands, which will have many consequences. Effective environmental design can be providing a proper framework based on the landscape ecology by defining the city's proper functions, it will protect these natural arenas.
