The timely and precise detection of forest fires is critical for halting the spread wildfires minimizing ecological economic damage. However, large variation in target size complexity background UAV remote sensing images increase difficulty real-time fire detection. To address this challenge, study proposes a lightweight YOLO model (LUFFD-YOLO) based on attention mechanism multi-level feature fusion techniques: (1) GhostNetV2 was employed to enhance conventional convolution YOLOv8n...
Carbon storage is an important component of ecosystem services. Under climate warming and human activities, land use/land cover (LULC) have been undergoing tremendous change, leading to spatio-temporal variations in carbon storage. Based on seven series LULC data combined with module Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model, spatial-temporal changes types were analyzed estimated for Heilongjiang Province, Northeast China. Results show varied among different LULC....
Financial management in universities is an important functional area that concerns the interests of teachers and development school. This article designs implements a smart financial system under digital campus framework to address problems current reimbursement system, such as multiple funding approval processes, information asymmetry, delayed communication between approvers personnel. Firstly, this analyzes characteristics drawbacks management, based on existing drawbacks, sorts out...
With the development of computer technology, forest fire spread simulation using computers has gradually developed. According to existing research on spread, models established in various countries have typical regional characteristics. A model a specific region is only suitable for local area, and there still great deal uncertainty as whether or not same fuel other regions. Although many been established, characteristics applicable each model, such loading, moisture content, combustibility,...
Background The prediction accuracy for the rate of surface fire spread varies in different regions; thus, increasing local fuel types to reduce destructive consequences is critically needed. Aims objective this study improve Rothermel model’s predicting ROS burning planted forests Pinus koraiensis eastern mountains north-east China. Methods Fuel beds with various loads and moisture content was constructed on a laboratory bed, 276 combustion experiments were performed under multiple slope...
We cloned a Cinnamoyl‐ CoA Reductase gene ( BpCCR1 ) from an apical meristem and first internode of Betula platyphylla characterized its functions in lignin biosynthesis, wood formation tree growth through transgenic approaches. generated overexpression suppression lines analyzed them comparison with the wild‐type terms content, anatomical characteristics, height biomass. found that could increase content up to 14.6%, underexpression decreased by 6.3%. Surprisingly, modification expression...
Accurate understanding of lake water dynamic changes is beneficial to sustainable utilization resources and maintenance ecological balance. Lake change sensitively reflective climate environment change. This study chooses plateau plain as the area, uses Landsat TM/ETM+/OLI meteorological data source. Based on Google Earth Engine platform, areas are extracted using NDWI method, morphological characteristics analyzed. The model between factors area established analyzed in sections according...
Fungi were isolated using a rose bengal chloramphenicol agar as the culture medium. Congo red staining was used on sodium carboxymethyl cellulose medium to screen fungal strains that have potential produce cellulolytic enzymes according index (CI). The ability of these isolates break down holocellulose in three forest litter substrates (broad-leafed: Juglans mandshurica; coniferous: Larix gmelinii; broadleaf-conifer mixed: J. mandshurica and L. gmelinii) tested over 80 days incubation....
PM2.5 is one of major pollutants emitted from forest fires. High concentration not only affects short-term human respiration health, but also poses a long-term threat to cardiopulmonary functionality. Therefore, it great importance quantitatively assess the released by combustion in fire studies. In this study we examine relationships between and environment fuel characteristics laboratory experiments. experiments, beds with controlled moisture contents loads were first built; then 144...
Fertilizer application plays a crucial role in the decomposition of white poplar leaf litter and cycling nutrients within forest ecosystems. The impact various fertilizer additions on nutrient is poorly understood. In this study, seven treatments were conducted at following levels: Control (CK), no adding mineral fertilizers, N fertilization (+N), P (+NP), N, P, K (+NPK), (+PK), manure (+MF), bird fertilizers (+BF) plantation Qadis district, used litterbag techniques to measure mass...
Fire is one of the dominant disturbances in China's forest. Forest fires are strongly influenced by weather and climate. Recently, climate has been warming as a result an increasing concentration greenhouse gases aerosols global atmosphere composition. temperature rise kept same pace with warming. Such likely to have significant impact on forest fires. This study based northeastern China, area projected become hotter drier under change. Aiming at occurrence regularities Jilin Province, new...
Abstract Spot fire increase the difficulty of fire-fighting and threaten public safety, therefore it is important to study ignition probabilities fuel bed by different firebrands, in order understand mechanisms analyze formation spot fires. This will provide an basis for further improve efficiency reduce casualties. In this study, larch ( Larix gmelinii ) beds with moisture levels packing ratios diffreent including cones twigs sizes, was investigated. Ignition experiments were conducted at...
The survival probability of a tree exposed to surface fire varies widely depending on its bark. To advance the understanding insulation properties bark, mean thickness (BT), moisture content (MCb), structure (BS) and density (ρb) bark samples Mongolian oak (Quercus mongolica) (n=395) for four diameter classes were investigated. In addition, data from 158 heating experiments simulating low-intensity fires in laboratory used assess relative importance these affecting thermal evaluate...
The Daxinganling Region, in Heilongjiang Province, China, has experienced considerable losses to forest resources owing a recent increase fire frequency. This necessitates the predictions of behaviour this region, which requires assessment fuel moisture content (FMC) at appropriate space and time intervals. Here, we compare extrapolate results vapour-exchange methods for predicting hourly contents downed wood. FMC larch birch twig fuels was measured 1-h intervals different slope positions...
