Abstract

The invention provides a method for non-destructively monitoring grassland plant species diversity. Utilizing the flexible and easy-to-operate features of UAVs, and supporting corresponding aerial photography, recording, and statistical methods, a wide range of grassland plant species diversity monitoring has been realized, effectively solving the problem of low efficiency and destructiveness in the traditional measurement of grassland plant species diversity. , high operating costs, poor space-time comparability, and difficulty in large-scale long-term monitoring; high efficiency, low cost; non-destructive; long-term, fixed-point, and monitoring in specific environments can be achieved.

Description

technical field [0001] The invention belongs to the technical field of grassland plant species diversity monitoring, in particular to a non-destructive monitoring method for grassland plant species diversity. Background technique [0002] Species diversity is an important content of grassland ecosystem protection and rational utilization research. Traditional quadrat and transect measurement methods are relatively mature, and have formed relatively fixed parameters to characterize species diversity. After a long period of actual operation, we found that the existing methods have disadvantages in the following aspects, which are specifically reflected as follows: [0003] 1. High input cost, low efficiency, poor timeliness and limited representativeness: the sampling process of sample method or transect method requires a lot of labor, and the work progress is slow, resulting in high investment, poor timeliness and limited representativeness of this method; [0004] 2. It is ...
