Soil erosion, as one of the most significant worldwide environmental problem, is a dynamic water-related process, controlled by natural and anthropic factors, causing serious losses of fertile topsoil. Previous contributions show warning loss rates of soil resource for the EU territory: a total annual soil loss of 950 megatons, with an average rate of 2.4 t\/ha\/yr, smaller than the one for Romania of 3 t\/ha\/yr (EC, JRC), increasing values featuring areas with high dynamics of the land cover\/use pattern. The project aims to develop an integrated approach for soil erosion mapping and modelling in temperate regions from Romania, based on remote sensing (RS) data and GIS techniques. The research is organised between three main levels: (1) a RS and GIS-based potential soil erosion modelling approach, in order to quantify the potential soil loss rates for specific temporal moments, to analyse the potential soil erosion changes and predict future trends; (2) a RS-based soil erosion mapping approach for detecting the spatial locations and intensity classes of the affected areas, by integrating various Earth Observation imagery and data mining techniques; (3) an integrated approach for land cover\/use – soil erosion relationship analysis through in-situ measurements. The main outcomes (methodologies and geospatial database on national and local levels) represent essential and required instruments among scientists and policy-makers for decision making and sustainable space planning.<\/p>

Eroziunea solurilor, unul dintre cele mai r\u0103sp\u00e2ndite hazarde la scar\u0103 global\u0103, este un proces dinamic ce determin\u0103 pierderi importante ale orizontului superior de sol, bogat \u00een materie organic\u0103. Cercet\u0103ri anterioare arat\u0103 pierderi importante de sol pentru teritoriul UE: o pierdere anual\u0103 total\u0103 de 950 megatone, cu o rat\u0103 medie de 2,4 t\/ha\/an, mai mic\u0103 dec\u00e2t cea pentru Rom\u00e2nia de 3 t\/ha\/an (EC, JRC), valorile ridicate fiind specifice arealelor cu o dinamic\u0103 accentuat\u0103 a acoperirii terenurilor. Scopul proiectului este de a dezvolta o abordare integrat\u0103 pentru cartografierea \u0219i modelarea eroziunii solurilor \u00een Rom\u00e2nia, bazat\u0103 pe tehnici de teledetec\u021bie \u0219i SIG. Cercetarea este organizat\u0103 \u00een trei etape principale: (1)o abordare GIS pentru modelarea poten\u021bialului de eroziune a solurilor, cu scopul de a cuantifica poten\u021bialele pierderi de sol pentru diferite momente temporale, de a detecta schimb\u0103rile din ultimii 35 de ani \u0219i de a prognoza evolu\u021bia ratei de eroziune poten\u021bial\u0103; (2) o abordare bazat\u0103 pe integrarea datelor de Observarea P\u0103m\u00e2ntului cu tehnici de data mining pentru extragerea automat\u0103 a reparti\u021biei spa\u021biale \u0219i intensit\u0103\u021bii eroziunii solurilor; (3)analiza rela\u021biei dintre acoperirea\/utilizarea terenurilor \u0219i eroziunea solurilor. Principalele rezultatele (metodologii \u0219i baze de date geospa\u021biale) constituie instrumente necesare pentru cercet\u0103tori \u0219i factori decizionali, \u00een scopul formul\u0103rii \u0219i adopt\u0103rii m\u0103surilor ameliorative \u0219i planific\u0103rii durabile a spa\u021biului geografic.<\/p><\/p>\n","protected":false},"excerpt":{"rendered":"
