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 land use change model: Integrating landscape pattern indexes and Markov-CA

Ecological Modelling, 2014
Abstract Landscape pattern indexes are quantitative descriptions of the spatial composition and configuration of land use, which can influence a variety of ecological phenomena. In this paper, we propose a land use change simulation model based on landscape pattern indexes, Markov chain and cellular automata.

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 ...

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

Weighted misclassification rate: a new measure of classification error designed for landscape pattern index

Remote Sensing Letters, 2012
Thematic maps classified from remotely sensed data are usually used to derive landscape pattern index (LPI). As the classification error can propagate into the LPI calculation, correctly estimating the LPI error caused by the classification error is necessary in order to obtain a reliable landscape analysis.

Preliminary Comparison of Landscape Pattern–Normalized Difference Vegetation Index (NDVI) Relationships to Central Plains Stream Conditions

Journal of Environment Quality, 2002
ABSTRACTWe explored relationships of water quality parameters with landscape pattern metrics (LPMs), land use–land cover (LULC) proportions, and the advanced very high resolution radiometer (AVHRR) normalized difference vegetation index (NDVI) or NDVI‐derived metrics.

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

Detecting Spatiotemporal Dynamic Landscape Patterns Using Remote Sensing and the Lacunarity Index: A Case Study of Haikou City, China

Environment and Planning B: Planning and Design, 2007
Quantifying the landscape pattern and its dynamics is essential for the monitoring and assessment of the ecological consequences of urbanization. As one of the Special Economic Zones, Haikou is one of the fastest growing regions among all Chinese cities, owing to rapid real estate development.

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 ...
