The assessment of sustainability in cropping system is an important issue for natural resources management and environmental protection. Incorporating the geographical information system (GIS) and remote sensing (RS) technologies, an initial idea of the crop sustainability assessing system was thus proposed, based on ecosystem services value (ESV) assessing criterions. The system is basically constituted by two major parts, which were net primary production (NPP) based ESV evaluating system and universal soil loss equation (USLE) based conserving soil and water (CSW) evaluating system. The input datasets includes temporal moderate resolution satellite images (HJ‐CCD), Meteorological data, DEM data and soil data. To test the efficiency of the proposed system, an assessment was thus conducted along the Huai river watershed. The results showed that the value of sustainability for the study area was
