Influence factors of spatial variability of soil heavy metal contents along roadside;

Study on spatial variability of lead content under flue-cure tobacco (Nicotiana tabacum) leaf in Hunan Province,China;

Spatial variability of heavy metals in soil of Three-Gorges Reservior in Chongqing;

Simulation of soil arsenic spatial variation property in Xinyi and Donghai agricultural area using sequential gaussian simulation technique;

Study on spatial variation of infiltration rates for small watershed in loess plateau;

Influence of the spatial variation of soil pH on soil available potassium in banana plantation;

Studying the spatial variance characteristics of soil P is an important work for the soil nutrient management, and help developing best management practices (BMPs) to control the agricultural non-point P pollution.

Analysis on spatial variance of organic matter and available nitrogen of red soil surface layer in the hilly area of Longyou,Zhejiang province by geo-statistic and GIS resulted that the semivariogram for soil organic matter was well fitted by spherical model,while that for logarithm conversion value of alkaline hydrolysable nitrogen(AHN) was the same.

Spatial variations of ten kinds of soil nutrients and soil pH value were studied at Dushu nutrient monitoring village in Shaoxing City, Zhejiang Province, which was located on alluvial plain, and the characteristics of spatial variance were obtained from geostatistic analysis on soil nutrients.

That means the spatial heterogeneity of TP was mainly impacted by structures and that of other soil nutrients were impacted by both structures and random factors.

Geostatistics combined with geographical information system(GIS) techniques were applied to a treatment and analysis of the spatial heterogeneity of soil nutrients in topsoil(0—20cm) at Hailun County of Heilongjiang Province.
