soil and land information is vital for land use planning and infrastructure development. maps of soils landscapes are powerful tools to guide sustainable planning and natural resource management. fuzzy set theory has been widely used in soil science for soil classification and mapping, land evaluation, fuzzy soil geostatistics, soil quality indices. in fuzzy logic-based approaches, soil spatial...

In much of the world, large scale soil maps which would better inform land use decisions are not available. The major impediment to collection of large scale data is the cost of field survey over large areas. One promising approach to increase the efficiency of soil survey is soil-landscape modelling. Soil-landscape models formalise relationships between soil attributes and other environmental ...

Planning for land use development, protection of good quality agricultural land, land degradation management and many other resource management issues requires reliable land resource information. Enhanced Resource Assessment (ERA) techniques were employed to rapidly assess and predict soil and landscape attributes throughout Cooloola Shire in South East Queensland. ERA uses landscape modelling ...

knowledge about spatial soil variation in terms of measured pedodiversity offers the possibility to estimate the quality and variance within a soil map. diversity indices and abundance distribution models are statistical tools which ecologists have applied for decades for analyzing the intrinsic regularities of various ecological entities. in this study relationships between soils evolution, la...

Soil sealing (loss of soil resources due to extensive land covering for the purpose of house building, road construction etc.) and subsequent soil landscape pattern changes constitute typical environmental problems in many places worldwide. Previous studies concentrated on soil sealing in urbanized regions, whereas rural areas have not been given sufficient attention. Accordingly, this paper st...

bility arises mainly from the limitations of the discrete data model and from the polygon-based mapping pracA geographical information system (GIS) or expert knowledgetice employed in conventional soil surveys. based fuzzy soil inference scheme (soil-land inference model, SoLIM) is described. The scheme consists of three major components: (i) a Zhu (1997a,b), Zhu and Band (1994), Zhu et al. mod...

Subalpine forest ecosystems influence global carbon cycling. However, little is known about the compositions of their soil microbial communities and how these may vary with soil environmental conditions. The goal of this study was to characterize the soil microbial communities in a subalpine forest watershed in central Montana (Stringer Creek Watershed within the Tenderfoot Creek Experimental F...

The investigation into ecotones enabled a better understanding of the causal relationships between certain landscape elements, landscape utilisation categories and ecotones. By studying ecotones, we wanted to expand understanding of patterns having an influence on the landscape condition, structure, functions, landscape elements and their relationships. For better understanding and modelling of...

Understanding how plant trait-species abundance relationships change with a range of single and multivariate environmental properties is crucial for explaining species abundance and rarity. In this study, the abundance of 94 woody plant species was examined and related to 15 plant leaf and wood traits at both local and landscape scales involving 31 plots in subtropical forests in eastern China....

The paper reviews a set of soil surveys carried out in Iran using a geopedologic approach for different surveying aims in different scales. Most of these studies have implemented a similar survey method including the following steps: delineation of landforms from air photos using geomorphic and soil-landscape relationships, field check of the delineations, sample areas inventory with soils clas...
