The suitable spectral mode in remote sensing is often desirable to facilitate the inversion of ecological environment and landscape. This paper put forward an optimizing model based on variable precision rough sets (VPRS) for the land cover discrimination in wetland inventory.
The terrestrial export of dissolved organic nitrogen (DON) is associated with climate, geography and land use, and thus is influenced by geo-climatic variability, human interference, the farmland and woodland in soil, and hydrological connection levels to rivers.
This paper looks more closely at the sources of patent growth in the United States since 1984. It confirms that the increase is largely due to U.S. patenters, with an earlier surge in Asia, and some increase in Europe.
Remote sensing images can be used to delineate variations in the area of lakes and to assess the influence of environmental changes and human activities.
Rangeland degradation by livestock threatens several restricted-range species, but is largely overlooked by conservation biologists.
Farm production is surrounded by uncertainty. Between planting and harvesting manyrandom events such as plagues, droughts and sudden changes in commodity prices, may affectfarmers’ revenues.
