The Yellow River Delta, with the most typical new wetland system in warm temperate zone of China, is suffering from increasingly serious salinization. purpose this study to utilize five surface parameters, including Albedo (the Albedo), NDVI (vegetation index), SI (salinity index),WI (humidity and IFe2O3 (Iron oxide construct 10 different feature spaces and, then, propose two kinds monitoring models (point-to-point model point line model) soil results showed that inversion accuracy space...
Current feature space models of desertification were almost linear, which ignored the complicated and non-linear relationships among variables for monitoring desertification. Fully considering influencing factors process in Naiman Banner, four sensitive indices including MSAVI, NDVI, TGSI, Albedo have been selected to construct five spaces. Then, precisions different information (including linear models) compared analyzed. The Albedo-MSAVI model Banner has higher efficiency with overall...
The current desertification feature space models are almost linear and ignore the complicated nonlinear relations that exist among variables when monitoring desertification. Herein, point-to-point point-to-line have been proposed by completely considering between Albedo-Modified Soil Adjusted Vegetation Index (MSAVI) effects of soil background. Further, applicability these for different levels information was compared analyzed. model exhibited a larger inversion accuracy (93.8%) Naiman...
Abstract Under the stress of global change, rocky desertification has become a serious environmental problem in Karst Mountain area. At present, few remote sensing monitoring research works on based feature space model have been conducted and reported. In this study, Albedo-LST index point-point proposed, subsequently spatio–temporal evolution pattern driving mechanism Dafang district from 1986 to 2019 were analyzed. The results show that: (1) good applicability with overall accuracy 90.79%;...
From the fruits of Kochia scoparia (L.) Schrad, five triterpenoid glycosides were isolated for first time from this plant. They elucidated as momordin Ic, 6′-methyl ester IIc, He, 2′-O-β-D-glucopyranosylmomordin and IIc on basis spectral chemical methods. The last two saponins are new natural products.
Abstract The use of ligand SAP produces the cyanhydrins (III) with up to 70% e.e.
Based on the existing DWG data of Huludao City, basic geospatial information framework huludao city was established by using AutoCAD, FME and ArcGIS. Among them, after loading CASS, AutoCAD has a powerful graphics processing function, which makes it easy for original to meet storage standards; As conversion software, completed lossless between MDB solved biggest problem in this experiment. ArcGIS processing, modeling analysis functions. DEM is generated platform, series operations such as...
By taking the Landsat-7/ETM+ remote sensing images at two different time phases in Liaoyang, Liaoning, as basic data, this paper proposes a method of describing FVCs from three aspects space, time, and characteristic variations, to obtain spatial temporal variation scales research region through sensing-based PCA NDVI-based pixel dichotomy, summarize characteristics FVC diagrams phases. Results reveal that: (1) spatially, decline among which, most significant lies southeastern part, where...
The ecological environment in the northwest of Liaoning Province is very sensitive and fragile, it a national first-level ecologically fragile zone, frequency drought disasters high. It has great destructive power to healthy development agriculture, affects overall crop grain reserve Province, endangers stability production, life economy. According regional characteristics, based on MODIS data monitor situation cultivated land, select four periods 2002, 2009, 2014 2019, extract NDVI LST...
