The progress (evolution) of a civilization based on natural resources development has resulted in permanent natural environment destruction. By the beginning of the third millennium it has become evident that exploitation of the planet's mineral resources, being the basis for the existence and progress of civilization, is the cause of the global environmental crisis. The Mining Institute has substantiated a methodology of restoration of natural ecosystems (ecological restoration), which consists in using an idea o...

The paper emphasizes the ecological restoration (renaturation) of the natural conditions of a saline soil, which was previously under long term melioration. The soil is a Salinic Pelic Alluvic Sodosol with relict gleization, covering an Alkali soil (according to SRTS-2012). The site is located in Moldova Tableland, where Tma is 584.6?C and Pma is 9.5 mm. The depth of the groundwater table is about 1.80 m, with frequent seasonal fluctuations and weak-moderate mineralization. The soil had a polyphasic evolution, bot...

The paper deals with the implementation of modern techniques and methods of surveillance in closed mining sites, for monitoring, assessing the real state and forecasting possible changes to provide an integrated picture of the state of the natural environment. The proposed system is designed as a tool with practical applicability in the decision making process of ecological restoration strategies of closed mining sites. Closed / abandoned mines have an acute need to deploy a sensor network due to their lack of wor...
