Abstract

The invention provides a citrus plot value index calculation method and device, and relates to the field of land value evaluation.The citrus plot value index calculation method comprises the steps that to-be-measured data of a designated area is obtained, the to-be-measured data is calculated according to a per mu yield calculation formula, and a per mu yield coefficient is obtained; calculating the to-be-tested data of the research area according to an interference factor calculation formula to obtain an interference factor coefficient; according to an analytic hierarchy process, index weight calculation is carried out on the indexes of the research area to obtain an index weight coefficient, and according to a multiply-add composite algorithm, the index weight coefficient is calculated to obtain a suitability coefficient; and obtaining a commissioning coefficient of the research area, and calculating the per mu yield coefficient, the interference factor coefficient, the suitability coefficient and the commissioning coefficient according to a land parcel value index calculation formula to obtain a land parcel value index. The method fully considers the difference of regional yields, avoids the calculation of factors such as errors, increased production age limit, plot rent and pest and disease damage caused by manual participation, and improves the accuracy of plot value index calculation results.

Description

Technical field [0001] The present invention relates to the field of land value assessment, and more particularly to a calculation method and apparatus for citrus block value index. Background technique [0002] Citrus mainly includes mandarin, orange, orange, pomelo, etc., high nutritional value, medicinal value and health value, deeply loved, with the deepening and production and operation needs, some farm To be restructured, value assessment is required for this type of business asset of citrus orchard. Citrus production value needs to consider multiple aspects: First, the actual benefits are required to consider market economy; second, the year of citrus size is required; the third is the gap gap between the existing tree trend, soil, irrigation conditions, etc .; four It is the difference in citrus varieties; the five is the land occupancy fee; six is ​​the unpredictable losses caused by natural disasters, pests and diseases. [0003] In the prior art, some of the basic data...
