Embodiment Construction

[0074] A method for monitoring the biomass of floating Enteromorpha. Ship monitoring is carried out at the border of the green tide, and the distribution mode of floating Enteromorpha at sea is recorded. It is divided into three modes: sporadic distribution, striped distribution, and large-area patchy distribution. The effective monitoring area is calculated. In order to further calculate the green tide biomass and predict the short-term green tide arrivals. Specific steps are as follows:

[0075] The first step is to confirm the influencing factors of the measurement site observation.

[0076] The sea state has a certain influence on the observation, and the on-site investigation should be carried out in the weather without fog as much as possible. In the sea state above level 3 (see Table 1), the on-site investigation should be avoided as much as possible.

Abstract

The invention provides a floating enteromorpha biomass monitoring method so that to solve the problem that the Enteromorpha biomass still cannot be obtained accurately. The method is characterized bycomprising the following steps that 1, observation influence factors in the measuring site are determined; 2, a rapid monitoring tool is assembled, and the angle of the tool is regulated well; 3, a research vessel runs on the selected research fracture surface at the constant speed, and area recording is conducted by using the rapid monitoring tool in the step 2; 4, the monitoring area is recordedunder three different situations; 5, the enteromorpha area is calculated under three different situations; and 6, the enteromorpha biomass in a certain area is calculated. The method achieves measurement of the biomass of floating enteromorpha by adopting the vessel to monitor the area and the special-purpose measuring tool, the enteromorpha biomass is obtained more accurately, data support is provided for follow-up pre-warning and fishing work of enteromorpha, and thus manpower and material resources can be accurately prepared for pre-warning and fishing of enteromorpha.

Description

technical field [0001] The invention and the field of marine monitoring, in particular, relate to a method for monitoring floating Enteromorpha biomass. Background technique [0002] Since June 2008, the natural disasters of Enteromorpha in the Yellow Sea, the East China Sea and the coastal waters of Qingdao have come rapidly, with large scale, long duration and difficult disposal. Thousands of square kilometers, millions of tons of Enteromorpha floating on the sea, and a large number of floating Enteromorpha is approaching the waters of Qingdao, seriously endangering the coastal environment of Qingdao. [0003] In January 2009, Volume 31, Issue 1 of the Acta Oceanographica Sinica, the article "Enviromorpha Disaster Satellite Remote Sensing Emergency Monitoring and Monitoring System and Its Application" mentioned that the use of the National Satellite Ocean Application Center is based on the compatibility requirements of emergency and business operations, in "H On the basis...
