Annually, millions of hectares forest lands around the world are destroyed by fires. To minimize fire-caused losses, more studies on risk prediction fires need to be carried out. For predicting in cloud-rich areas (e.g., southwest China), synergetic use operational forecasting systems and remote sensing-based models is expected have a consistent performance. Therefore, we proposed this study new model based ant-miner algorithm which has good capability solving multivariable non-linear...
In recent years, global forest fires have occurred more frequently, seriously destroying the structural functions of ecosystem. Mapping burn severity after is great significance for quantifying fire’s effects on landscapes and establishing restoration measures. Generally, intensive field surveys across burned areas are required effective application traditional methods. Unfortunately, this requirement could not be satisfied in most cases, since work demands a lot personnel funding. For...
Temperature vegetation dryness index (TVDI) in a triangular or trapezoidal feature space can be calculated from the land surface temperature (LST) and normalized difference (NDVI), has been widely applied to regional drought monitoring. However, thermal infrared sensors cannot penetrate clouds detect information of sub-cloud pixels. In cloudy areas, LST data include large number pixels, seriously degrading spatial temporal continuity this paper, Remotely Sensed Daily Land Surface...
Most of the existing object detection methods have complicated hand-designed components, such as non-maximum suppression procedures and manual resizing anchor boxes. Based on DETR, this paper not only eliminates need for component adjustment, but also solves three problems poor remote sensing image directional capture, slow DETR convergence, same attention allocated by different layers Decoder. First, D-Angle module is used to align rotating region while accelerating convergence using a...
Fine particulate matter (PM2.5) has attracted extensive attention due to its harmful effects on humans and the environment. The sparse ground-based air monitoring stations limit their application for scientific research, while aerosol optical depth (AOD) by remote sensing satellite technology retrieval can reflect quality a large scale thus compensate shortcomings of measurements. In this study, elaborate vertical-humidity method was used estimate PM2.5 with spatial resolution 1 km temporal...
Landslide is one of the most serious geological disasters, and effective way to prevent disaster forecast. In this paper, landslide regionalization model induced by precipitation used through analyzing in-depth risk rating models, implemented refinement forecast system in district level based on GIS secondary development approach. The main function achieve result information management. forecasting results obtained can provide a scientific basis for local government departments such as...
According to different ecological conditions of various sweet orange and the consumption fresh processing orange, article determined main index climate factors, which impact growth citrus, based on major resources meteorological disasters citrus in Three Gorges reservoir area. This studied spatial distribution average annual total solar radiation, temperature relative humidity by methods regression, simulation, interpolation with help ARCGIS 1:250000 DEM (Districts counties 1:50000). In...
This paper choose MODIS product data of single-day and 8d synthesis from June to September in 2006 construct vegetation supply water index (VSWI) for Chongqing summer drought condition, validated results by soil moisture; while the correlation between VSWI precipitation is discussed, spatial temporal distribution were gotten using synthetic data.The showed that: (1) E built EVI was more suitable monitoring than N NDVI, has better 8-day data; (2) had a certain negative with precipitation; (3)...
Modeling fire susceptibility in fire-prone areas of forest ecosystems was essential for providing guidance to implement prevention and control measures fires. Traditional models were developed on the basis random selection absence data (i.e., nonfire from unburned areas), which could bring uncertainties modeling results. Here, a new model with genetic algorithm Rule-set Production (GARP) 10 environmental layers proposed process presence-only fires Chongqing city. To do this, 70% 684...
Chongqing city locates at the foothill, where Jialing River and Yangtze joins. A severely high temperature drought occurred in summer of 2006. So, it has been very necessary urgent to know affection trend extent urban heat island during that period. The data measured automatic weather stations was used statistic island. High resolute numeric model simulate distribution its influences temperature. researches showed there a clear phenomenon Chongqing. average daily intensity 1.0°C maximal...
Light use efficiency (LUE ) is an important parameter for GPP and NPP estimation model, cause by the existing model method to estimate actual LUE always simple rough, which may lead serious bias NPP. The photochemical reflectance index ( PRI has great potential direct LUE. In this paper, wheat in different nitrogen treatments was designed field trial during Wheat growing period, obtain photosynthesis reflective hyperspectral data, then calculated critical period of growth. results show that,...
The paper analyzed the current situation and development trends of China's tobacco industry established a value chain model. At last, determines enterprise competitive advantage by decomposing activities.
It is a simple and efficient way to complete the custom program according GIS spatial analysis function supported by ArcGIS Geoprocessing. In this paper, Geoprocessing technology based on plug-in Secondary development used build drought remote sensing monitoring system. The 2006 data in Chongqing was processed as an example for system, models suitable were selected. Compared traditional manual processing, system's automation degree has been greatly improved enhanced, which can accurate...
Missing values in land surface temperature (LST) data are often observed the cloud-sheltered area, thereby seriously limiting spatiotemporal continuity of LST. In this work, Remotely Sensed Daily Land Surface Temperature Reconstruction model(RSDAST) is used to gap-fill pixels sheltered by clouds FY-3 C/VIRR Result shows that cloud VIRR and MODIS original LST (OLST) product can be reconstructed accurately, but reconstruction accuracy better compared based on RSDAST model. addition, decreases...
