Embodiment Construction

[0043] A method and device for researching chlorophyll fluorescence characteristics of aquatic plants in Jiuzhaigou proposed by the present invention, its specific implementation is as follows:

[0044] 1. The present invention proposes a research method and device for the chlorophyll fluorescence characteristics of aquatic plants in Jiuzhaigou. On the basis of many field investigations, according to the distribution of the water system in Jiuzhaigou, Fangcaohai, Jianzhuhai and Wuhuahai are selected as research samples. land.

[0045] 2. The Fangcao Lake is a long strip of seas distributed along the ditch, with an altitude of 2934m. Haizi is 540m long, 92.2m wide, generally 2-4m deep, and has an average area of ​​5.21ha for many years. Sediment deposits can be seen at the tail of the Fangcao Sea, the main source of which is the relatively developed tributaries in the vicinity of the Fangcao Sea in a northwest-southeast direction (the southeast side is the virgin forest branch...

Abstract

The invention relates to a method and a device for researching the chlorophyll fluorescence characteristic of Jiuzhaigou Valley aquatic plants, relates to research on photosynthesis characteristic of aquatic plants and relation between the aquatic plants and a water environment, and belongs to G01 type. The device consists of a pulse modulation chlorophyll luminoscope capable of being controlled remotely and an electric remote control catamaran with an underwater robot. The method comprises four parts of chlorophyll fluorescence characteristic measurement, photosynthetic active radiation intensity and water temperature measurement, chlorophyll content measurement and data analysis. By the device and the method, remote real-time sampling, monitoring and experiment are realized, the working environment of scientific research personnel is greatly improved, and the working efficiency is improved; and the device is maneuverable, data is detailed and accurate, the method is reasonable, analysis is complete, graphs are attractive, and great scientific research theoretical and practical significance is achieved.

Description

[0001] (1) Technical field: [0002] The invention relates to a research method and device for the chlorophyll fluorescence characteristics of aquatic plants in Jiuzhaigou, and relates to the research on the photosynthetic characteristics of aquatic plants and their relationship with the water environment, belonging to the G01 category. [0003] (two) background technology: [0004] At present, some lakes in Jiuzhaigou have obvious silt deposits, and the problem of lake swamping is serious. Accompanied by the sedimentation of the lake and the input of a large amount of nutrients, aquatic plants grow in large numbers. Some scholars have studied the sedimentation-promoting effect of aquatic plants in East Taihu Lake, and the results show that the sedimentation effect caused by biological organic matter is more significant, accounting for about 20.8%-64% of the average depth of sediment, and the sedimentation-promoting effect of aquatic plants is very significant . In this way, ...
