Double Cropping

Time-series satellite images can reflect the seasonal variation from vegetation on land surface. Single cropping and double cropping were extracted by decision tree classification based on MODIS NDVI of Beijing in 2007, and spatial distribution of dominant crops in Beijing was obtained. The dominant crops of single cropping were maize, wheat and vegetable, and the overwhelming majority of crops with double cropping were wheat-maize. The results showed that this method could effectively determine the dominated crops in Beijing.

The article describes a method of mapping climatic parameters (i. e. frequency and intensity) of severe weather events, based on the interpolation of weather station data. We applied regression-based interpolation, using some geographical variables (altitude, slope angle and curvature) for modeling their spatial distribution. Statistically significant correlations between geographical and climatic variables were selected based on regression analysis. They have been used to create a maps of frequency, average and maximum intensity of severe weather events for Perm region (160 600 km2). The proposed method allows to create more accurate and detailed maps of spatial distribution of severe weather events than traditional deterministic and geostatistical interpolation methods. The reliability of the results confirmed by a weather station observations and comparisons with MODIS satellite images thematic products. Significant advantage of proposed method is also its applicability to the risk assessment of severe weather events in ungauged site, or in ungauged areas.

Abstract In the last few years, Romania’s forests have become one of the most interesting and most talked about topics for an increasing number of researchers from the most varied fields, both nationally and internationally. The present study aims at analyzing as accurately as possible the forests of Iasi County, especially forests with primary functions of protection, following the changes occurred after 1990 and the way these affected the functional framing of the forests and their state. This research has been accomplished based on precise statistical data collected from every region (or forestry district), these in turn being matched with maps, satellite images and aerial imagery.

Abstract. This study focused on landslides along mountain roads that were caused by Typhoons Nanmadol (2011) and Kong-rey (2013). Image interpretation techniques were employed to interpret satellite images captured before and after the typhoons to derive the changes in slope surfaces. The multivariate hazard evaluation method was adopted to establish a landslide susceptibility assessment model. We then mapped landslide susceptibility and locations to determine the relationship between the spatial distribution of landslide areas and the natural environment along mountain roads. The results can serve as a reference for preventing and mitigating slope disasters on mountain roads.
