Abstract

The invention provides a method for non-destructively monitoring the species diversity of grassland plants. By utilizing the characteristics of flexibility and simplicity in operation of the unmannedaerial vehicle and matching with corresponding aerial photography, recording and statistics methods, large-scale grassland plant species diversity monitoring is realized, and the problems of low efficiency, destructiveness, high operation cost, poor space-time comparability and difficulty in large-scale long-term monitoring of traditional grassland plant species diversity measurement are effectively solved; high efficiency and low cost are achieved; no damage is caused; and long-term, fixed-point and specific environment monitoring can be realized.

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 ...
