Scaling Correction of Remotely Sensed Leaf Area Index for Farmland Landscape Pattern With Multitype Spatial Heterogeneities Using Fractal Dimension and Contextural Parameters

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018
High-accuracy retrieval of the crop leaf area index (LAI) in farmlands via remote sensing is the premise of reflecting the true growth condition of the crop. This paper aimed at scaling correction of LAI retrieval and developed an LAI scaling transfer model for farmland landscape pattern with multitype spatial heterogeneities according to the multiple ...

The influence of landscape fragmentation, expressed by the ‘Effective Mesh Size Index’, on regional patterns of vascular plant species richness in Lower Saxony, Germany

Landscape and Urban Planning, 2016
Abstract Landscape fragmentation has been identified as a major threat to biodiversity worldwide. Several landscape metrics have been developed to quantify the extent of fragmentation, of which the Effective Mesh Size Index (meff) is one of the most widely used. However, its relevance for analysing the effect of fragmentation on biodiversity patterns

Optimization of PM2.5 Estimation Using Landscape Pattern Information and Land Use Regression Model in Zhejiang, China

Atmosphere, 2018
The motivation of this paper is that the effect of landscape pattern information on the accuracy of particulate matter estimation is seldom reported. The landscape pattern indexes were incorporated in a land use regression (LUR) model to investigate the ...
