Embodiment 1

[0063] A sustainable management evaluation method for a ginkgo composite management system. First, calculate the load matrix to determine the scale and establish a judgment matrix; then the matrix is ​​normalized after row averaging, and the consistency test is performed on each matrix according to the randomness index value ;Finally, the single factor weight of each layer is combined with the weight of the previous layer, and the combined weight is calculated, and the values ​​of each index are linearly weighted and summed to obtain the comprehensive evaluation value. Specific steps are as follows:

[0064] 1) Divide the goal of decision-making, factors considered (decision criteria) and decision-making objects into the highest level, middle level and lowest level according to their interrelationships, and draw a hierarchical structure diagram: the highest level: the purpose of decision-making, to be solved The lowest layer: the alternatives for decision-making; the middle la...

Embodiment 2

[0109] Adopt the method of embodiment 1, carry out on-the-spot evaluation. According to the survey data, the afforestation time of ginkgo forest was 1994, the distance between plants and rows was 8m×8m, and the height of grafted parts was 1.2-1.5m. The compound business model includes 1994 ginkgo + rape (Brassica campestris L.) + peanut (Arachis hypogaea) (94G+R+S), 1994 ginkgo + wheat (Triticumaestivum L.) + peanut (94G+W+S), 1994 Ginkgo + mulberry (Morus alba L.) (94G + M), with 1994 ginkgo (94G), rape + peanut (R + S) as the control. The ginkgo trees built in 1994 have a DBH of 19.7-31.4cm, a tree height of 6.0-7.8m, and a crown width of 5.9-8.8m. The row spacing of mulberry trees is 30cm×1m, and the height is controlled within 2.0m by pruning. The fertilization amount and fertilization method of each mode are consistent (the fertilizer is compound fertilizer, which is spread once a year when crops are planted in May and September, and the fertilization amount is 375kg hm ...

Abstract

The invention discloses a sustainable management evaluation method for a ginkgo composite management system, and the method comprises the steps: firstly calculating a load matrix so as to determine the scale and build a judgment matrix; secondly carrying out the row averaging and normalization of the matrix, and carrying out the consistency verification of all matrixes according to a random index value; finally combining the single factor weight of each layer with the weight of a last layer, calculating the combined weight, carrying out the linear weighting and summation of the values of all indexes, and obtaining a comprehensive evaluation value. According to the invention, the load matrix is calculated, and the objective quantitative evaluation and comparison of importance degrees of all factors. A simple and clear comprehensive analysis method is build, and the quantified element levels are built. The correlation among all layers, all rules and all elements is clearly presented. Through the system thinking rule, the method combines the decomposition, judgment and integration system evaluation modes, achieves the quantitative sustainable management evaluation of the ginkgo composite management system, and achieves the multi-target, multilayer and multi-rule sustainable management and decision-making analysis for the ginkgo composite management system.

Description

technical field [0001] The invention can be applied to efficient utilization of land and ecological factor resources, improvement of yield and quality of ginkgo wood and other products, protection of ecological environment and sustainable management of land, and the like. The invention relates to a sustainable management evaluation method of a ginkgo compound management system, specifically, a multi-objective, multi-level and multi-criteria sustainable management decision-making analysis method for a ginkgo agroforestry compound management system. First, calculate the load matrix to determine the scale and establish a judgment matrix; then the matrix is ​​normalized by row average, and the consistency of each matrix is ​​checked according to the randomness index value; finally, the single factor weight of each layer is compared with the above A layer of weight combination is used to calculate the combination weight, and the values ​​of each index are linearly weighted and summ...
