Mobile cultivated land quality and/or cultivated land productivity investigation and evaluation system and method

Abstract

The invention belongs to the technical field of cultivated land investigation and evaluation, and relates to a mobile cultivated land quality and / or cultivated land productivity investigation and evaluation system and method, and the system comprises a field data collection subsystem and a cultivated land quality and / or cultivated land productivity evaluation subsystem. The field data acquisitionsubsystem comprises a mobile platform, an unmanned aerial vehicle image acquisition device, a portable quick test device and a sample acquisition and storage device. The mobile platform is divided into a driving area, an operation area and a bearing area. The driving area meets the driving requirement and monitors the operation area and the bearing area. The operation area meets the field operation requirement and stores portable instruments. Large instruments are stored in the bearing area. The system is compact in structure, complete in function, convenient to operate and capable of quicklyand effectively completing farmland quality investigation and evaluation and improving the investigation and evaluation efficiency. The evaluation method is comparable in nation and county, is an effective expansion of the existing evaluation method, and greatly improves the universality and applicability of the method.

Description

technical field [0001] The invention belongs to the technical field of cultivated land survey and evaluation, and relates to a survey and evaluation system and a survey and evaluation method, in particular to a system and method for rapid survey and evaluation of cultivated land conditions, especially to a mobile cultivated land quality and / or cultivated land productivity Survey evaluation systems and methods. Background technique [0002] Cultivated land quality consists of many elements, involving climate, topography, soil, infrastructure and other aspects, and the spatial distribution of each element is extremely complex. There are also many types of cultivated land quality survey equipment, including sample collection equipment (such as: shovel, pick, shovel, drill, profile knife, soil cutting knife and ring knife, etc.), field observation and description equipment (such as: ruler, compass, color card, etc.) and reagents, etc.), field rapid measurement equipment (such a...

AI Technical Summary

Problems solved by technology

[0003] 1. The investigation equipment that can be carried at one time is very limited;

[0004] 2. Larger equipment is inconvenient to carry;

[0005] 3. The detection instrument does not have enough room for operation, and cannot play its due role, etc.

[0006] Traditional cultivated land quality survey equipment has the problems of single function, poor integration and low flexibility, which makes traditional cultivated land quality survey difficult, high investment, and time-consuming; furthermore, it is difficult to quantitatively describe some elements of cultivated land quality and cultivated land productivity, and the survey data is too large. , complex processing process and cumbersome evaluation process, etc.

[0007] At the same time, there are already multiple versions of cultivated land quality and cultivated land productivity index systems in the existing technology, such as "Research on County-level Farmland Quality Evaluation Method under the Four Quality Dimensions" (Xin Yunna et al., "Resource Science", Volume 40, Issue 4 ) based on the theoretical framework of "demand-quality dimension-indicator-limitation coefficient-cultivated land quality", starting from human demand for cultivated land, based on agricultural land quality grading, basic soil fertility evaluation and environmental requirements of green food production areas, and leading Based on the principles of conservation, protection, regionality, and social acceptance, comprehensively considering the four dimensions of cultivated land soil quality, ecological quality, environmental quality, and management quality, multiple indicators that have an impact on each quality dimension of cultivated land are selected, but these selected indicators Most of them also have limitations; in the existing patents CN107403253A, CN107657270A, CN107516168A, CN107860890A, CN107958448A and CN108805421A, etc., the disclosed methods for detecting cultivated land quality and cultivated land productivity and related methods cannot meet the general needs of the whole country , so it is necessary to further innovate and improve the selection of the index system
