“…This is also in agreement with the CV value and CA mentioned in the above sections. Our results are in contrast to the results of Bai et al (2010b), which is conducted in different land uses in Siping area of Jilin Province. Their results showed that there was a rather large difference in the effects of Cr, Ni, Cu, As, Cd and Zn accumulation in soils under greenhouse field, uncovered vegetable field, maize field and forest field land uses.…”

Vegetation and different land uses may affect the spatial distribution of heavy metals in soils. The objective of the current article was to study the impact of industrial activities and land use type on the distribution of heavy metals in soils of Chitgar Forrest Park, located in industrial zone in the west of Tehran City. The soil samples were taken from 116 sites in a regular sampling grid (250 9 250 m) at a depth of 0-20 cm, including three different land uses, needle leaf forests, broadleaf forests and rangeland. Nitric acid-extractable form of seven metals, Cu, Cd, Fe, Mn, Ni, Pb and Zn, and DTPA-extractable form of Cu, Fe, Mn and Zn were measured. Soil texture, pH, organic carbon, carbon-to-nitrogen ratio, percentage of calcium carbonate and electrical conductivity (EC) were also determined. According to the maps and background amounts, heavy metals were affected by industrial activities and road traffic. Proximity to heavy traffic highway of Tehran-Karaj and large autoindustry plants can be considered for increasing metal concentrations. Results of statistical methods (coefficient variation and cluster analysis), besides geostatistical analysis (variogram and map), showed that total concentrations of heavy metals are controlled by intrinsic and extrinsic factors in the studied area. Although land use type did not affect the alteration in the distribution of total concentrations of heavy metals, it changed the distribution of DTPA form of heavy metals in the soils through affecting the soil organic matter.

“…4, the first and fourth quadrants). This is consistent with the result reported by Bai et al 44, that uncovered field held higher accumulation of heavy metals. Hobbs et al 45 and Querol et al 46 presented that the main influencing factors for plant growth in reclaimed areas were the soil nutrients, heavy metal contents, and acid pollutions.…”

Water samples and vegetation data in 1 m Â 1 m vegetation quads (vegetation density, biomass, and size were investigated) were collected from Panyu District and reclaimed regions with different reclamation histories in Nansha District throughout the Pearl River Estuary in August 2010. The spatial distribution characteristics of Fe, Cu, and Mn in the surface water system were measured based on ordinary Kriging method of ArcGis Geostatistical Analyst. Metal index (MI) was selected to assess the pollution levels and principal correlation analysis (PCA) was chose to interpret the effects of these heavy metals on vegetation. Results showed that (i) there were higher concentrations of Fe and Cu appearing in the up west than that in the other parts of the whole region, meanwhile, a similar spatial distribution was showed in Fe and Cu, which indicated the two kinds of metals came from the same pollution source; (ii) all the MI values exceeded class I level and the water quality in metal levels was over or equal to class III level in the whole research region, and worse water quality was presented in the middle west of Panyu District and in the old reclamation region in Nansha District due to the characteristic of the surface water system and the long-term tillage, respectively; (iii) the concentrations of Fe and Cu showed negative correlation with vegetation, and Mn nearly had no effects on vegetations, and 1/3 of all samples were seated in the higher coverage and lower pollution area, which belongs to the new reclamation in Nansha District.

“…Schwarz et al (2012) found that the concentration of soil Pb was related to individual landscape features at a patch scale and to the landscape matrix where these patches were embedded. Landscape heterogeneity is a result of variation of soil properties and parent material (Krami et al, 2013;Mico et al, 2006), land use pattern and change (Bai et al, 2010;Wu et al, 2013), the distance to specific potential pollution sources (Chrastny et al, 2010;Gu et al, 2012;Luo et al, 2011;Nanos and Rodriguez Martin, 2012), and landscape pattern or matrix (e.g., bedrock geology, road length, and number of industries; Deschenes et al, 2013;Lin et al, 2002). These properties are useful proxies to quantify some trace metal pollutants.…”
