“…The occurrence of dust storms is not only the result of natural factors but also the result of human activities, including overgrazing and deforestation, which reduce vegetation coverage [21]- [24]. Therefore, the variation trends of dust storms are analyzed together with other indicators of land use/cover changes using a long-term observation data series.…”

To reveal the multivariate relationships between man-made and meteorological factors on dust storm frequency, the LUCC data, NDVI remote sensing data and meteorological data for the period of 1983-2013 were combined with dust storm frequency data, and the possible impacts of meteorological and anthropogenic factors on dust storm frequency were analyzed by using regression analysis and PCA (Principal Component Analysis). Results show that the inter-annual dust storm frequency increased gradually. In particular, an increasing trend in recent years, after 2009, is conspicuous. The monthly frequency of dust storms shows higher values between the months of February and May, with the highest mean number of events occurring in April, which accounts for 29% of the annual dust storm frequency. The annual dust storm frequency is positively correlated with wind speed and negatively correlated with precipitation; the monthly dust storm frequency is positively correlated with wind speed, but no significant correlation can be found with precipitation. The relationship between temperature and dust storms is not simply linear, however, a certain correlation with an unremarkable statistical significance can be found between them. Human activities also affect the dynamics of dust storms indirectly via changing vegetation coverage and direct dust emissions. The multivariate analysis further confirmed the association between dust storm frequency and meteorological factors and NDVI. The high loadings of dust storm frequency, wind speed, precipitation and NDVI on a PC indicate that the increased precipitation and NDVI will decrease dust storm frequency, and increased wind speed will increase dust storm frequency.

“…Elevated nutrient concentrations can lead to eutrophication or hypoxia of streams, lakes, and estuaries. Research generally attributes increasing nutrient concentrations to changes in climate (Park et al, 2010;Shrestha et al, 2011) or demographic factors including land-use alterations (Duh et al, 2008;Shi et al, 2010). Reducing nutrient loadings from wastewater treatment facilities and implementing BMPs that target specific types of land use are the typical means for mitigating excess nutrient enrichment in surface water (Bechmann et al, 2008;Dowd et al, 2008;Marsden and Mackay, 2001).…”

“…1 Given that URTR is an ecological sensitive area, its land-use/land-cover changes have links to both human and nature interactions, monitoring the change of land use/land cover (LU/LC) over this region is helpful to create its harmonious coexistence pattern between man and nature and maintain its sustainable development in the future [1]. There are some existing researches focuses on the land use cover change of URTR, such as: Yongliang (2010) analyzed the changes (from 1994 to 2005) of population, land use patterns and water resource based on integrated methodology of GIS and statistic data [2].Zumrat Ebrayimland use and land cover change and trends and environmental effects of the period 1960 to 2000 were analyzed and researched quantitatively using mathematical statistical methods. Most the existing study focus on the land use cover changes before 2010 [3].…”
