Abstract
Pine Wilt Disease (PWD) is spreading globally, and the failure to timely detect and clear Discolored and Deceased Pine Trees (DDPT) carrying the pine wilt will further exacerbate the spread of PWD in affected regions. To address the necessity of recognizing the DDPT removal information, this research constructs a highly robust Discolored and Deceased Pine Trees network (DDPTnet) for DDPT detection. Additionally, by integrating detection results from DDPTnet with dual-period UAV Digital Orthophoto Models (DOM), Digital Surface Models (DSM), and a scene classification algorithm (DDPTnet-cls) based on DDPT, the current gap in DDPT removal information monitoring has been addressed. In the three monitoring areas, DDPTnet achieved an average F1 score (F1) of 87.31 % for DDPT detection. By integrating the detection results of DDPTnet with dual-period DSM, the average F1 score (F1-la) for logged area extraction was 94.59 %, and the average F1 score (F1-l) for identifying logged DDPT was 82.08 %. The DDPTnet_cls classification method, after fine-tuning, achieved an average classification accuracy (Acc) of 77.91 %. Finally, based on the above results, The “DDPT Removal Information Thematic Map” were produced. These outcomes can provide objective and effective decision support for the prevention and control of PWD outbreaks.
期刊介绍:
The journal ''Remote Sensing Applications: Society and Environment'' (RSASE) focuses on remote sensing studies that address specific topics with an emphasis on environmental and societal issues - regional / local studies with global significance. Subjects are encouraged to have an interdisciplinary approach and include, but are not limited by: " -Global and climate change studies addressing the impact of increasing concentrations of greenhouse gases, CO2 emission, carbon balance and carbon mitigation, energy system on social and environmental systems -Ecological and environmental issues including biodiversity, ecosystem dynamics, land degradation, atmospheric and water pollution, urban footprint, ecosystem management and natural hazards (e.g. earthquakes, typhoons, floods, landslides) -Natural resource studies including land-use in general, biomass estimation, forests, agricultural land, plantation, soils, coral reefs, wetland and water resources -Agriculture, food production systems and food security outcomes -Socio-economic issues including urban systems, urban growth, public health, epidemics, land-use transition and land use conflicts -Oceanography and coastal zone studies, including sea level rise projections, coastlines changes and the ocean-land interface -Regional challenges for remote sensing application techniques, monitoring and analysis, such as cloud screening and atmospheric correction for tropical regions -Interdisciplinary studies combining remote sensing, household survey data, field measurements and models to address environmental, societal and sustainability issues -Quantitative and qualitative analysis that documents the impact of using remote sensing studies in social, political, environmental or economic systems
