Ramsar Convention (RC) is the first of modern intergovernmental agreement on the conscious use and conservation of natural resources. It provides a platform for contracting parties working together to develop the best available data, advice, and policy recommendations to increase awareness of the benefits of wetlands in nature and society. Turkey became a party of the RC in 1994, and in the years 1994 to 2013, 14 wetlands that reached the Ramsar criteria were recognized as Ramsar sites (RS). With this study, all inland RS in Turkey from 1985 to 2020 were examined, and changes in the water surface areas were evaluated on the GEE cloud computing platform using Landsat satellite images and the NDWI index. The closest meteorological station data to each RS were evaluated and associated with the surface area changes. The reasons for the changes in these areas, besides the meteorological effects, have been scrutinized using management plans and publications. As a result, inland wetlands decreased at different rates from 1985 to 2020, with a total loss of 31.38% and 21571.0 ha for the spring months. Since the designation dates of RS, the total amount of water surface area reduction was 27.35 %, constituting 17,758.90 ha.

使用谷歌地球引擎分析土耳其内陆拉姆萨尔湿地的时间变化

拉姆萨尔公约 (RC) 是第一个关于有意识地使用和保护自然资源的现代政府间协议。它为缔约方提供了一个平台，共同开发最佳可用数据、建议和政策建议，以提高对湿地对自然和社会效益的认识。土耳其于1994年加入RC，1994年至2013年间，14处达到拉姆萨尔湿地标准的湿地被认定为拉姆萨尔湿地（RS）。通过这项研究，对 1985 年至 2020 年土耳其所有内陆 RS 进行了检查，并使用 Landsat 卫星图像和 NDWI 指数在 GEE 云计算平台上评估了水面面积的变化。评估最接近每个 RS 的气象站数据并将其与表面积变化相关联。除了气象影响外，这些地区变化的原因还通过管理计划和出版物进行了仔细检查。结果，内陆湿地从 1985 年到 2020 年以不同的速度减少，春季总减少了 31.38% 和 21571.0 公顷。自 RS 指定日期以来，水表面积减少总量为 27.35 %，构成 17,758.90 公顷。
