The outcome indicated that the gridding while the kernel thickness analysis improved the accuracy of spatial evaluation and reflected the spatial superposition and diffusion impacts. In the extensive individual task intensity chart of Lashihai watershed, the highest intensity worth of water area was at the mouth of this ocean, the cheapest strength value was at the biggest market of the sea, and the total trend of power gradually decreased from the surrounding to the middle. The land settlement had the greatest power, the intensity value of the farming land gathering area was at the middle degree, plus the power of real human tasks when you look at the forestry area of higher height was lower. The extensive individual activity intensity within the water area of the Lashihai watershed diverse most demonstrably, and differed considerably through the basic personal activity intensity. Though there had been many local characteristic tourism activities in Yunnan-Guizhou Plateau Wetland scenic area, however their land use kinds performed not modification. We need to take all of them into consideration when quantifying the strength of individual activities.In order to simplify the eco-environmental quality and its own development traits of Keluke Lake basin, we picked 15 facets of real location, meteorology, land use/cover and social economic climate utilizing extensive investigation, remote sensing interpretation and inversion, analytical analysis and other technical means, based on the relevant ideas of environmental ecology. We used aspect analysis and entropy method to determine the index weight, constructed watershed soil quality model and environmental environment quality analysis design, and analyzed the modifications of earth and eco-environmental high quality within the Keluke Lake basin in 2000, 2005, 2010 and 2015. The outcomes showed that the average eco-environmental high quality in four durations had been 21, 47, 54, and 72, showing a stable ascending trend. The eco-environmental high quality level changed from poor to good, while soil high quality is at the middle level. Spatially, the eco-environmental top-notch the northern mountainous area, the downstream wetland plus the surrounding area of the lake improved substantially. The change of eco-environmental quality had been due to personal tasks and normal elements. Soil quality and lake area had been important aspects suggesting the eco-environment regarding the Keluke Lake basin. The minimum ecological water demand of this Keluke Lake had been the basic guarantee to steadfastly keep up the harmless development of the eco-environment associated with pond basin.Based in the MODIS NDVI data from 2000 to 2018, we estimated the fractional plant life cover (FVC) with the dimidiate pixel design and examined the spatiotemporal attributes of FVC within the Beijing-Tianjin sand supply area (BTSSR). The geographical detector design ended up being used to calculate the impacts of normal and peoples factors on FVC spatial distribution at the local scale. The results showed that the FVC regarding the BBTSR revealed a growing trend from 2000 to 2018, with an annual development price of 0.013·(10 a)-1 and a vegetation increase rate of 8.2per cent. The location with high FVC was concentrated within the Yanshan Mountain liquid resource protection location, followed by the pastoral transitional zone desertified land control location plus the Otindag sandy land location. The region with bad FVC was focused Mucosal microbiome within the northern arid grassland area. The explanatory power of driving elements to FVC varied across different regions. On the list of natural aspects, yearly precipitation ended up being the primary driving element for the spatial distribution of he spatial variants of FVC. The product range of suitable plant life development identified by the danger detector had been the area with annual precipitation of 316.4-486.0 mm, typical general moisture of 48.4%-57.6%, and normal yearly heat PTU of 2.5-7.9 ℃, while other driving factors had been various in numerous zones.Rainfall intensity, slope size, and slope gradient would be the critical indicators impacting runoff and deposit yield. In order to quantitatively analyze the results of rainfall intensity, pitch size, and slope gradient on the erosion procedure for Ansai loess slope in loess hilly and gully region, we analyzed the difference of runoff and sediment yield on Ansai loess with two slope lengths (5, 10 m), three slopes (5°, 10°, 15°) as well as 2 rain intensities (60, 90 mm·h-1) in an inside simulated rainfall Nonsense mediated decay research. The outcome showed that the initial runoff generation time decreased with the increases of slope length, although the total modification was not considerable. The initial runoff generation time reduced with the increases of rain strength. Weighed against the strength of 60 mm·h-1, the original runoff generation time diminished by 5.7-18 min beneath the power of 90 mm·h-1. Among them, the runoff initiation time from the slope of 10° ended up being the fastest.
