National forest resource continuous checking cloud platform and sample plot monitoring method

Abstract

The invention relates to a national forest resource continuous checking cloud platform and a sample plot monitoring method, the cloud platform comprises a sensing layer, a network layer, a platform layer, a data layer, an application layer and a user layer, and the invention provides a sample plot monitoring method, through executing checking sample plot reset and equipment layout, checking sample plot data automatic acquisition, and checking sample plot dynamic monitoring management, the data of the checking sample plot can be automatically acquired. According to the method, a national forest resource continuous checking cloud platform is operated, manual investigation is replaced by automatic monitoring, a national forest resource continuous checking work organization mode is changed, fixed time interval investigation is replaced by real-time monitoring, and the working efficiency is improved. According to the invention, national forest resource continuous checking global and all-weather real-time continuous monitoring is realized, the organization and guarantee difficulty of forest sample plot investigation work is greatly reduced, the investigation work danger is reduced, the investigation work and personnel technical requirements are reduced, the investigation work quality control difficulty is reduced, and the repeated work of investigation and quality inspection work is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things and geospatial data collection, calculation and processing, and in particular relates to a cloud platform for continuous inventory of national forest resources and a method for monitoring sample plots. Background technique [0002] The National Forest Resources Continuous Inventory is the highest-level macro-level forest resources survey and monitoring in the forest resources survey system. It conducts a re-test survey on the set fixed sample plots by the method of sampling survey, and uses the principles and methods of mathematical statistics to carry out the data obtained from the survey. Analysis, in which the fractional sampling method is used to estimate the area of ​​each type in the population, the systematic sampling method is used to estimate the accumulation amount of each type, and the growth and consumption are calculated using the reset log. Through repeated and comparative...

Problems solved by technology

[0004] (1) The time interval is long, and it is impossible to truly meet the annual output requirements

There are 415,000 fixed sample plots in the country. Due to the huge workload, the continuous inventory of national forest resources can only be completed every 5 years. Only joint estimation and other methods can be used to statistically calculate the forest area and forest coverage of the whole country and provinces (autonomous regions, municipalities). forest stock volume, forest stock volume per unit area, growth per unit area, and other total forest resource data cannot truly achieve annual output and cannot meet the needs of the government and society for dynamic monitoring of forest resources

[0005] (2) The investment in the investigation is large, and the organization and guarantee are difficult

There are 415,000 fixed sample plots across the country, which are arranged by systematic sampling. For the actual measurement sample plots, investigators need to arrive at the site for measurement. The continuous inventory of national forest resources consists of organization, training, trial production, production, inspection, summary and result statistics. , it needs to consume a lot of manpower and material resources, and the national work organization and guarantee investment is huge. If annual monitoring is achieved, it will be difficult to organize and guarantee

[0006] (3) The investigation work is arduous and dangerous

The continuous inventory of national forest resources adopts systematic sampling layout, and some of the inventory sample plots are in no-man’s land. In addition, the actual measurement sample plots need to be reset manually and the sample trees must be measured. difficult, dangerous
