This paper presents the results of a study aimed at assessing the eŒects of input uncertainty on the outcome of a raster-based model for structural landscape classiŽ cation. The model uses a DEM and a land-cover map as input, and calculates four structural indices from these data. The Ž rst two indices determine the openness of the landscape, the other two determine the degree of landscape homo...

As a regulator of ecological environment, Baiyangdian Wetland is in pivotal position constructing the blue-green space (BGS) Xiong’an New Area China. This study aims to reveal spatiotemporal changes BGS from 2016 2021. It uses Google Earth Engine (GEE) calculate NDVI and NDWI based on Sentinel-2 Satellite remote sensing data extracts by classification model driven NDWI. Moreover, land-use trans...

Studies of spatial patterns of landscapes are useful to quantify human impact, predict wildlife effects, or describe various landscape features. A robust landscape index should quantify two components of landscape diversity: composition and configuration. One category of landscape index is the contagion index. Some landscape ecologists promote the use of relative contagion indices. It is demons...

This study aims to analyse sea use landscape patterns on a regional scale based on methods of landscape ecology integrated with sea use spatial characteristics. Several landscape-level analysis indices, such as the dominance index, complex index, intensivity index, diversity index and sea congruency index, were established using Geographic Information System (GIS) and applied in Huludao, China....

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...

Under rapid urbanization, many cities in China suffer from serious fine particulate matter (PM2.5) pollution. As the emission sources or adsorption sinks, land use and the corresponding landscape pattern unavoidably affect the concentration. However, the correlation varies with different regions and scales, leaving a significant gap for urban planning. This study clarifies the correlation with ...

rangeland ecosystem contains various patches with different functions. structural and functional characteristics of rangeland patches are changed by management practices and can be used to interpret management effects. the structural and functional characteristics of fertilized patches in two rangeland ecosystems of ghareh ghir and maraveh tapeh were measured and analyzed in this study. a group...

Analyzing spatial and temporal changes in landscape patterns is an important aspect of landscape ecology. We used satellite imagery and ERDAS Image software, calculated landscape indices, and quantified landscape transformation processes to determine the nature and magnitude of landscape structural changes within an upland area of the Taishan Mountains in Shandong province, eastern China. We us...

Landscape indices are popular for the quantification of landscape pattern. However, all landscape indices being used so far are scalar quantities, and measure patterns without considering sufficiently the pattern shape and the directionality together. Based on planar characteristics defined in mechanics such as centroid, moment of inertia, product of inertia and principal axes, vector analysis ...

Understanding the development of landscape patterns over broad spatial and temporal scales is a major contribution to ecological sciences and is a critical area of research for forested land management. Boreal forests represent an excellent case study for such research because these forests have undergone significant changes over recent decades. We analyzed the temporal trends of four widely-us...
