The correlation analysis on the landscape pattern index and hydrological processes in the Yanhe watershed, China

Journal of Hydrology, 2015
Summary Yanhe watershed, as a typical and experimental district of Soil and Water Conservation District, has long been plagued by soil erosion due to severe human disturbances. Exploring the relationship between watershed landscape pattern and hydrological processes can find effective ways to solve soil erosion problems. At first, with remote sensing

Spatiotemporal estimation of the PM2.5 concentration and human health risks combining the three-dimensional landscape pattern index and machine learning methods to optimize land use regression modeling in Shaanxi, China

Environmental Research, 2022
PM2.5 pollution endangers human health and urban sustainable development. Land use regression (LUR) is one of the most important methods to reveal the temporal and spatial heterogeneity of PM2.5, and the introduction of characteristic variables of geographical factors and the improvement of model construction methods are important research directions ...

Landscape pattern analysis based on GIS technology and index analysis

Cluster Computing, 2017
Based on the 2014 forest resource second-class investigation data and DEM data of Yabuli forest park, we used the GIS technology and Fragstats4.2 analysis software, and adopted the 2-class classification system including land-use type and dominant tree species to analyze the composition elements, patch characteristics and spatial distribution of ...

A new contagion index to quantify spatial patterns of landscapes

Landscape Ecology, 1993
A contagion index was proposed by O'Neill et al. (1988) to quantify spatial patterns of landscapes. However, this index is insensitive to changes in spatial pattern. We present a new contagion index that corrects an error in the mathematical formulation of the original contagion index. The error is identified mathematically. The contagion indices (both

Landscape pattern and spatial variability of leaf area index in Eastern Amazonia

Forest Ecology and Management, 2005
Abstract Uncertainties about the implications of land-cover heterogeneity on the Amazonian carbon (C) and water cycles are, in part, related to the lack of information about spatial patterns of key variables that control these fluxes at the regional scale. Leaf area index (LAI) is one of these key variables, regulating a number of ecosystem processes

Integrating circuit theory and landscape pattern index to identify and optimize ecological networks: a case study of the Sichuan Basin, China

Environmental Science and Pollution Research, 2022
The notion of ecological networks (EN) and their identification can support approaches to nature conservation strategies aiming at biodiversity, landscape connectivity, and people's well-being. Integrating ecosystem services (ESs), morphological spatial pattern analysis (MSPA), circuit theory, and landscape pattern index analysis, we proposed a new ...
