Accurate monitoring of bare soil land (BSL) is an urgent need for environmental governance and optimal utilization resources. High-resolution imagery contains rich semantic information, which beneficial the recognition objects on ground. Simultaneously, it susceptible to impact its background. We propose a segmentation model, Deeplabv3+-M-CBAM, extracting BSL. First, we replaced Xception Deeplabv3+ with MobileNetV2 as backbone network reduce number parameters. Second, distinguish BSL from...
Net radiation plays an essential role in determining the thermal conditions of Earth's surface and is important parameter for study land-surface processes global climate change. In this paper, improved satellite-based approach to estimate daily net presented, which sunshine duration were derived from geostationary meteorological satellite (FY-2D) cloud classification product, monthly empirical as bs Angstrom coefficients shortwave calibrated by spatial fitting ground data 1997 2006, longwave...
There is a growing interest in quantifying regional scale actual evapotranspiration (ET) for water resource management. Using moderate-resolution Imaging spectroradiometer (MODIS) data, combination with meteorological records, an integrated approach proposed to estimate daily ET over 1-km grid covering North China. The Surface Energy Balance System (SEBS) adapted partition the sensible heat from latent heat. A gap-filling method estimation during cloudy intervals accomplished by of SEBS...
Sunshine duration is an important variable that widely used in atmospheric energy balance studies, analysis of the thermal loadings on buildings, climate research, and evaluation agricultural resources. In most cases, it calculated using interpolation method based regional-scale meteorological data from field stations. Accurate values are difficult to obtain without ground measurements. this paper, a satellite-based estimate sunshine introduced applied over Heihe River Basin. This hourly...
As dust source bare soil land (BSL) contributes to air pollution and affects the photosynthesis of green plants carbon absorption, it is objective this study develop an approach for monitoring changes BSL using remote sensing technology. Unlike other use/cover types, classification as well its change detection often ignored. For traditional convolutional neural networks, deep layers cause a long range between input output, inevitably leading loss information computational costs. To alleviate...
Data integration and sharing has been an important part of city data warehouse establishment application integration. It can let more people use existing resources fully, reducing duplication work on collection corresponding costs. Smart City needs to establish underlying exchange platform contact the entire systems, applications, sources, etc. So that meet need seamlessly share between government, business enterprise ERP, CRM, SCM, database, data. Multi-source heterogeneous research aims...
Agricultural drought given the significant impacts on social economy and human living, research agricultural monitoring has been paid broad attention by many scholars. Development of remote sensing technology provides a potential opportunity for effective real-time monitoring. Vegetation index, as one most important parameters to characterize vegetation growth monitor change, can effectively evaluate crop status. High resolution index time series not only feature changes affected time, but...
With the deepening use of public information resources in smart cities, platforms have been paid more attention as basic support platform for intelligent city application. At present, new urbanization construction is full swing China. Fine security management communities has become core urbanization. Smart community needs to integrate Internet Things (IOT), Mobile and other technologies seamlessly manage indoor outdoor data. In this paper, development technical framework Public Information...
The accurate extraction of agricultural burned area is essential for fire-induced air quality models and assessments grain loss wildfire disasters. present study provides an improved approach mapping uncontrolled cropland areas, which involves pre-classification using a difference vegetation index model various land scenarios. Land surface temperature was analysed in unburned areas integrated into previous burn scar (BSI) model, multispectral thermal infrared information were combined to...
Soil fugitive dust (SFD) is a significant contributor to environmental particulate matter (PM), which not only pollutes and affects air quality but also poses risks human health. The emission inventory can provide basis for the effective prevention control of SFD pollution. However, current inventories with low resolution frequency make it difficult assess emissions accurately. Obtaining monthly high-resolution bare soil information one solutions compiling inventories. Taking Daxing...
In this paper, a novel method to simulate soil heat flux for large spatial scale is proposed. This constructed with the ratio of and net radiation (G0/Rn) surface characteristic parameters, such as vegetation indices, temperature, shortwave infrared reflectance, moisture content, solar zenith angle. Field calibration carried out using measured data in 2009 from Yingke, Huazhaizi, Arou, Dayakou stations located Heihe River Basin, Northwest China. The estimated compared field observation...
Irrigation, metallurgy and other industrial with agricultural users are characterized by large loads high regularity of electricity consumption. Participation in demand response can play a huge role building new power system. At the same time, on basis regulating capacity multi-energy flow integrated energy system, adjustable demand-side resources be further improved. To this end, first, various equipment modeled, calculation model is proposed that takes into account respective operating...
