روش قرايت و ثبت مظاهر منظر فرهنگي

Recording and scanning method of cultural landscape manifestations.

در روند ارزيابي و بررسي ارزش‌هاي اجتماعي ـ فرهنگي اكوسيستم‌ها‌، شكاف‌هاي روش‌شناختي عميقي در حوزه مباحث مفهومي مرتبط با ارزش‌هاي زيباشناسانه، معنوي يا تاريخي آشكار مي‌شود. اين مقاله با اين فرض كه بهره‌برداري از منافع غيرعيني اكوسيستم‌ها ـ كه خدمات فرهنگي اكوسيستم يا به اختصار CES1 ناميده مي‌شوند ‌ـ آثار ملموسي بر منظر فيزيكي به جا مي‌گذارد، رويكرد جديدي را جهت شناخت اين منافع ارايه مي‌دهد. اين پژوهش نمودهاي عيني به جا مانده از كاربرد CES در منظر را در قالب يك تحليل ميداني از يك سايت رديابي و ثبت مي‌كند، سپس آنها را كمي كرده و با ابزارهاي بصري ـ فضايي مثل نقشه يا GIS تحليل مي‌كند. نتايج اين تحقيق، اطلاعاتي را در خصوص ويژگي‌ها، مفاهيم و نحوه توزيع فضايي CES ارايه مي‌دهد و امكان تحليل آنها را نيز از لحاظ تعامل با ويژگي‌هاي منظر يا مجموعه خدمات اكوسيستم فراهم مي‌كند. اين نتايج همچنين دو مزيت عمده اين روش را نشان مي‌دهد : 1) به عنوان رويكردي براي تجزيه و تحليل آماري و ادغام با داده‌هاي كمي و فضايي در ارزيابي جامع منظر مناسب است. 2) به عنوان نسخه‌اي ساده شده مي‌تواند داده‌هاي ارزشمندي را براي كاربردهاي تحقيقي يا مكمل توليد كند.

Ecosystem services has been defined as ‘‘the benefits people obtain from ecosystems” by MA, the Millennium Ecosystem Assessment. Some of these benefits are non-material which according to the MA definition, are obtained through ‘‘spiritual enrichment, cognitive development, reflection, recreation, and aesthetic experiences. These benefits are called cultural ecosystem services (CES) and include six subsets: Cultural identity, Heritage values, Spiritual services, Inspiration, Aesthetic appreciation, and Recreation and tourism. There is a strong linkage between CES and the determinants and constituents of human well-being, which made it important to recognize and analyze them. Attempts at assessing the values people attach to ecosystems reveal profound methodological gaps regarding the non-material domains associated with aesthetic, spiritual or heritage values. The methodological backbone of CES assessments is the conducting of qualitative interviews. But interviews for analyzing CES are necessarily intensive and in-depth; thus they can hardly be conducted using quantitative, standardized questionnaires. Data on other ecosystem services are mainly quantitative and therefore this makes it difficult to integrate study results into comprehensive reports on different types of ecosystem services. Data generated through typical interview techniques which do not integrate maps or photos into the process do not deliver spatially explicit data, making it hard to relate non-material values to a specific place or feature of the physical landscape. This paper presents a new approach for trying to grasp these intangible benefits based on the assumption that making use of CES leaves discernible marks on the physical landscape. We explore the potential for tracing visible manifestations of CES in a field walk-based landscape analysis in the district of Unterlenningen, the Swabian Alb in southwestern Germany. The general structure of this approach is to systematically record these manifestations of CES in the site, to quantify them using statistical methods and to integrate them into spatially explicit representations such as map or GIS. The results provide information on the character, significance, and spatial distribution of CES and allow for analysis in terms of correlations with landscape features or ecosystem services bundles. Based on our results, the method has two main strengths: 1) as an approach it is suitable for statistical analysis and integration with spatially explicit and quantitative data in comprehensive landscape assessment; and 2) as a simplified version it can generate valuable data for exploratory or complementary uses. However it has several limitations. Most importantly, not all types of CES can be captured adequately with this method; moreover, spatially explicit and quantitative data are provided only to a limited degree. Therefore, we see the benefits of this method mainly as a complement to other approaches, such as interviews with individuals, focus groups, and literature reviews. In this regard, the method of recording visible manifestations can be an important component of the multi-faceted toolbox which is indispensable for assessment of CES. Future application of the method may take two primary directions. First, it can be applied in a strictly systematic way, providing quantitative data suitable for all kinds of statistical analyses. Second, it is a simplified version of the method. A relatively rough quantification and spatial exemplification is needed in order to provide an overview of CES provisions or to derive exploratory insights of single CES types when comparing different investigation areas.
