Problems solved by technology
[0004] However, due to the remote location of the sea-island, arranging a large number of monitoring equipment in the sea-island environment to collect sea-island environmental data in real time will consume a large amount of power supply, communication and maintenance costs; The service life will be affected by the frequency of collection. If the sea-island environmental data is continuously collected in real time and continuously, the service life of the monitoring equipment will be shortened, resulting in the inability to collect the sea-island environmental monitoring data within the effective time period, resulting in the inability to Make an accurate assessment of the health of the sea-island environment

Embodiment Construction
[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0034] Such as figure 1 As shown, the sea-island environmental health monitoring method in this embodiment includes the following steps 1 to 8 in turn:
[0035] Step 1. Divide the previous cycle of the current cycle into n time domains with equal intervals according to the preset time interval, and obtain the sea-island environmental health measured data samples in the previous cycle to obtain the sea-island environmental health data samples in each time domain of the previous cycle. Island environmental health measured data sample; among them:
[0036] Let the current cycle be marked as T, the preset time interval be marked as Δt, and the previous cycle of the current cycle T be marked as T - ,T - =T - (t - 1 ,t - 2 ,...,t - n ); the previous cycle T - The sample of inland sea-island environmental health measured data is marked as ...

The invention relates to a sea-island environment health monitoring method. The sea-island environment health monitoring method includes the steps: separating the last time period into a plurality of time domains with equal time intervals by acquiring the measured data of sea-island environment health about the last time period of the current time period, and then obtaining the measured data sample variance yields of sea-island environment health, corresponding to each time domain; establishing the sea-island environment health data sampling density function in each time domain, and according to the obtained sea-island environment health data sampling density function corresponding to each time domain, uniformly sampling the sea-island environment health data sample corresponding to each time domain for the current time period; and utilizing a Kriging method to construct an implicit function model about time, of sea-island environment health, and taking the implicit function model through verification as a sea-island environment health model. After establishment of the sea-island environment health model, the cost of power supply and communication maintenance can be greatly saved; bad influence on the service life for the sea-island environment health data monitoring device because of too many sampling times can be avoided; and the monitoring efficiency for the sea-island environment health situation can be effectively improved.
Description
technical field [0001] The invention relates to the field of sea-island environmental monitoring, in particular to a sea-island environmental health monitoring method. Background technique [0002] The rapid development of the marine economy has had a series of impacts on the marine ecology and the environment. Promoting the healthy development of the marine economy and strengthening the protection of the marine ecological environment with information technology have good social benefits and broad application prospects. At present, the indicators that affect the marine ecological environment mainly include: seawater salinity, turbidity, dissolved oxygen, chlorophyll, pH value, various heavy metal content, intertidal zone and sea-island temperature, humidity and biological species, etc. [0003] In view of the increasingly strong demand for sea-island environmental health monitoring and evaluation of offshore, intertidal zone, island, coastal land environment and ecology, bas...
