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...

AI Technical Summary

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

[0007] (4) High requirements for investigation technology and quality

[0008] (5) It is difficult to control the survey quality

Due to the quality of the investigators and the objective situation of the survey work, there will be deviations such as sample wood reset failure, wrong measurement, and missed measurement during the investigation, which will affect the accuracy of the investigation results. Since the quality inspection work adopts random inspection methods, it is impossible to achieve comprehensive quality inspection. There is a fluke mentality in personnel, and the sample plot survey is started before reaching the location of the inventory sample plot, or even completely fabricated data indoors, which makes it difficult to control the quality of the survey

[0009] (6) Duplication of investigation and quality inspection work

Sample plot reset, sample tree reset, and each tree's ruler inspection are the most important tasks in the inventory survey. However, in actual work, most of the inventory sample plots exist and grow stably and continuously. Only individual advanced trees have changed, but they still need to Repeat the work of sample plot reset, sample tree reset and per-tree inspection, and the quality inspection work is also to select and check the sample plots, and then perform sample plot reset, sample tree reset and each tree inspection again. There are many problems in the investigation and quality inspection work. repetitive work

[0010] (7) Unable to grasp the change information of the inventory sample land in time

Only when the investigators investigate the inventory plots again, can they find out whether the inventory plots have changed, and the investigation cannot obtain the reasons and time of changes in the inventory plots in time
