The aim of the present study was to evaluate the microbial ecosystem of cultivated soils along the Evros river in NE Greece. Evros river together with its derivative rivers constitute the capital source of life and sustainable development of the area. Along this riverside watery ecosystem systematic agro-cultures were developed such as wheat, corn and vegetable cultures. The evaluation of the ecosystem microbial charge was conducted in both axes which are the watery ecosystem and the riverside cultivated soil area. Considerable discrimination of water quality was observed when considering chemical and microbiological parameters of the Evros river ecosystem. Ardas river possesses a better water quality than Evros and Erythropotamos, which is mainly due to the higher quantities that these two rivers accumulate from industrial, farming and urban residues leading to higher degree of pollution. An increased microbial pollution was recorded in two of the three rivers monitored and a direct relation in microbial and chemical charging between water and cultivated-soil ecosystems was observed. The protection of these ecosystems with appropriate cultivated practices and control of human and animal activities will define the homeostasis of the environmental area.
本研究旨在评估希腊东北部埃夫罗斯河沿岸栽培土壤的微生物生态系统。埃夫罗斯河及其支流构成了该地区生命和可持续发展的源泉。沿着这条河边的水生生态系统，发展了系统的农业种植，如小麦、玉米和蔬菜种植。对生态系统微生物负荷的评估是在两个轴线上进行的，即水生生态系统和河边栽培土壤区。考虑到埃夫罗斯河生态系统的化学和微生物参数，观察到水质有相当大的差异。阿尔达斯河的水质比埃夫罗斯河和埃里特里波塔莫斯河要好，这主要是因为这两条河从工业、农业和城市残留物中积累了更多的物质，导致了更高程度的污染。在所监测的三条河流中有两条记录到了微生物污染的增加，并且在水和栽培土壤生态系统之间观察到了微生物和化学负荷之间的直接关系。通过适当的耕作实践和控制人类和动物活动来保护这些生态系统，将决定环境区域的内稳态。
