The exotic species of mangrove wetland refers to non-indigenous mangrove plants distributed in the mangrove. The exotic tree species have quick growth property, strong adaptability and higher propagation body diffusion capacity, namely have obvious invasive plant characteristics, occupy the protogenic mangrove biotope, have increasingly serious ecological threat and save to evaluate the ecological risk in time. In the foreign mangrove survey process, tree height is one of important evaluation indexes. The height measurement of the tree is usually performed by using a height measuring device, such as a telescopic height measuring device, also called a sliding staff, generally having a specification of 10m, 12m, 15m, 20m, 25m and the like, each section of the rod is provided with scales, the height measuring device is folded when not in use, one or more investigators are arranged to operate the height measuring device and pull out gradually when in use, and the other investigator is arranged to observe whether the height measuring device reaches the position of the top of the tree or not. The height of the height finder is higher after the height finder extends out, so that the height finder is inconvenient to operate, and the top end of the height finder is difficult to find by an investigator, so that the height finding efficiency is lower. Therefore, it is necessary to develop a tree height measuring device for surveying the foreign species in the mangrove wetland, which can solve the above problems.
