This invention relates to an automated monitoring method for the dynamic changes of plant diversity in mountainous forest areas, comprising: constructing a three-dimensional model of the target mountainous area and deploying a sensor network; collecting microclimate data and soil characteristic data to determine a spatial distribution matrix; acquiring historical plant distribution data of the target mountainous area, mapping it to the spatial distribution matrix to construct a comprehensive distribution map of environmental factors, and determining a correlation model between plant distribution and environmental factors; acquiring real-time satellite remote sensing image data of the target mountainous area, using the correlation model to analyze the characteristics of changes in plant cover and plant diversity distribution, and locating several key plant distribution areas; identifying plant species and counting their numbers in the key plant distribution areas, updating the comprehensive distribution map of environmental factors, and completing the automated monitoring of the dynamic changes of plant diversity in the target mountainous area. This invention integrates multi-source environmental data to achieve automated analysis of plant diversity distribution.

The invention belongs to the technical field of species identification, and particularly relates to application of a detection reagent of InDel molecular markers for distinguishing acer truncatum lineages, two InDel molecular markers North and Soth for identifying acer truncatum populations are disclosed for the first time, the nucleotide sequence of the molecular marker North is as shown in SEQ ID NO.1, the nucleotide sequence of the molecular marker Soth is as shown in SEQ ID NO.2, the nucleotide sequence of the molecular marker North is as shown in SEQ ID NO.1, and the nucleotide sequence of the molecular marker South is as shown in SEQ ID NO.2. Molecular markers North and Soth can be used for distinguishing the southern pedigree and the northern pedigree of acer truncatum. The invention also develops a reagent for detecting the molecular marker, and develops a method for distinguishing the southern pedigree and the northern pedigree of the acer negundo, and the method can accurately and effectively identify the pedigree type of an acer negundo sample to be detected, distinguish the southern pedigree and the northern pedigree of the acer negundo, and improve the detection accuracy of the acer negundo. And an efficient and reliable technical means is provided for protection and research of acer truncatum.

This invention discloses a synergistic method for cold-season grazing and warm-season fertilization in alpine meadows, belonging to the field of alpine grassland ecological restoration and sustainable agricultural management technology. The method includes the following steps: using UAV remote sensing to acquire spatial distribution information of litter in the cold-season grassland, and dividing the grassland into patches with different litter loads based on this information, implementing differentiated grazing by region; using a soil sensor network buried in the grassland to monitor soil temperature and moisture content, dynamically defining the start and end times of cold-season grazing and the operational window for warm-season fertilization; during the warm season, spraying the grassland with liquid nitrogen and phosphorus fertilizer containing synergists according to the warm-season fertilization operational window. This invention deeply couples the physical disturbance of cold-season grazing with the chemical regulation of liquid nutrients in the warm season, solving problems such as slow litter decomposition, low fertilizer utilization, delayed greening, and decreased soil fertility in alpine meadows, achieving a synergistic improvement in grassland production and ecological functions.
