Problems solved by technology

[0003] However, the imprecise potential of agricultural residue resources, unclear spatial distribution, and unclear future potential are important reasons for restricting the energy conversion of agricultural residue biomass resources; through literature review, the evaluation methods of agricultural residue resource potential can be divided into statistical methods and There are two types of RS-GIS (Remote Sensing-GeoInformation system, remote sensing-geoinformation system) methods: the former refers to the use of statistical data such as land area and agricultural production to evaluate the resource potential of biomass history or current status, which is the resource potential evaluation of agricultural residues. The method with the earliest application time and the widest application range has the advantages of simplicity, ease of implementation, good reproducibility, and low cost; the disadvantage is that it is impossible to predict the potential of agricultural residue resources in the future; the current evaluation of the potential of agricultural residue biomass resources has the following problems: insufficient:
[0004] (1) Lack of current assessment of the potential of China's high-resolution agricultural residue reso

Example Embodiment

[0034] In order to make the objects, technical solutions and advantages of the present invention, the present invention is further detailed in connection with the accompanying drawings and examples. It will be appreciated that the specific embodiments described herein are intended to explain the invention and is not intended to limit the invention.

[0035] refer to Figure 1 to 3 , An agricultural residual residual resource potential evaluation method is:

[0036] a) Agricultural residual resource potential self-calibration evaluation model based on natural resources large data mainly includes five steps, one, determine the type of natural resources of the input natural resources; Second, combined with RS-GIS analysis and statistical analysis methods, build agriculture Residual resource potential assessment model (such as figure 1 Disted); 3, the model is running on the ArcGIS platform; Aspects are divided into current assessments and future estimates.

[0037] The status quo is e...

Abstract

The invention relates to an agricultural residue resource potential assessment method, which comprises the following steps: a) determining the type and parameters of input natural resource big data, the type and parameters being agricultural products and the number of the agricultural products; b) combining an RS-GIS analysis and statistical analysis method to build an agricultural residue resource potential assessment model, the RS-GIS specifically being a remote sensing-geoscience information system; c) running the model on an arcgis platform; d) outputting an agricultural residue resource potential evaluation result with the resolution of 1 kilometer; and e) further calibrating the model according to an input result to improve the accuracy of a model output result. According to the agricultural residue resource potential assessment method provided by the invention, the agricultural residue resource potential assessment precision is improved, crop types in agricultural residue resource potential assessment are enriched, the assessment year span is increased, and an estimation reference is provided for future agricultural residue utilization.

Description

technical field [0001] The invention relates to the field of potential evaluation of agricultural residue resources, in particular to a method for evaluating the potential of agricultural residue resources. Background technique [0002] Biomass resources refer to all kinds of organic matter formed through photosynthesis, which have industrial, agricultural and ecological purposes such as energy production, feed, and fertilizer. Among them, the proportion of agricultural residues composed of agricultural straw and agricultural product residues to biomass resources It is considerable, rich in resources, convenient to collect, and highly available; biomass energy is a carbon-neutral non-fossil energy that plays an important role in CO2 net zero emissions and negative emissions; according to the prediction of my country's biomass resource theory The amount of exploitable resources is 360GWh, but the exploited amount is only 14%. Therefore, identifying the potential of China's high...
