Abstract

The article reflects research, where for the first time mapping of benthic vegetation biotopes of the protected area “Coastal aquatic complex near the Dzhangul landslide coast” is carried out using GIS-technologies. The research is carried out on the basis of the expedition materials analysis collected in the coastal zone in the summer period of 2013. As a result of the work a bathymetrical map, maps of bottom sediments and habitats of the key macrophytobenthos species (Ericaria crinita, Gongolaria barbata, Nereia filiformis, Phyllophora crispa) and biotopes are compiled. Benthic vegetation biotopes classification is based on cartographic materials. Five biotopes are identified, described and analysed for their spatial distribution in the natural protected area. It is shown that biotopes with “Сystoseira” and Рhyllophora phytocenoses occupy the largest area in the coastal zone. These biotopes have a high conservation status at the regional, federal and international levels. In the deep-water zone of the protected area the biotopes with Nereia filiformis and Phyllophora crispa (drifting form), unique and rare for the Crimean coastal area have been identified. This area is found to be a peculiar reserve of both attached and drifting forms of Phyllophora crispa for the western coastal area of Crimea. Biotope classification and its conservation status are given according to international legislative documents (EUNIS, Annex 1 code, European Red List of Habitat). The development of a classification, mapping and inventory of habitats, and the preparation of a biotopes list in need of conservation, are urgent scientific tasks. The results can be used for monitoring protected benthic vegetation habitats and controlling their condition.
张桂海岸底栖植被群落的GIS制图
本文反映了首次利用gis技术对“张格勒滑坡海岸附近滨海水生复合体”保护区底栖植被生物群落进行制图的研究。本研究是在2013年夏季在海岸带采集的考察资料分析的基础上进行的。根据研究成果,绘制了海底等距图、海底沉积物图、主要大型底栖植物物种(白刺erica criinita, gonolaria barbata, Nereia filformis, Phyllophora crispa)栖息地图和生物群落图。底栖植被生物群落分类是基于地图资料。确定、描述和分析了自然保护区的五种生物群落的空间分布。结果表明,“Сystoseira”和“Рhyllophora”植物群落在海岸带的面积最大。这些生物群落在区域、联邦和国际层面都具有很高的保护地位。在保护区的深水区,已经确定了克里米亚沿海地区独特和罕见的生物群落,其中有丝状线虫(Nereia filiformis)和crispa Phyllophora(漂流型)。该地区被发现是克里米亚西部沿海地区的特殊保护区,既有附着形式,也有漂流形式。根据国际立法文件(EUNIS,附录1代码,欧洲生境红色名录),给出了生物群落分类及其保护现状。对生境进行分类、绘图和清点,并编制需要保护的生物群落清单,是紧迫的科学任务。研究结果可用于监测受保护底栖植物的生境和控制其状况。
