Herbivorous wildlife-based herbivorous wildlife balance assessment method

Abstract

The invention belongs to the field of ecological balance, and provides a herbivorous wildlife-based herbivorous wildlife balance assessment method. The method comprises the steps of delimiting an accounting area of herbivorous wildlife balance; evaluating the grassland bearing capacity of the accounting area based on remote sensing data; according to the livestock distribution information and the herbivorous wild animal distribution information, respectively calculating the livestock column storage amount and the herbivorous wild animal existing amount; calculating the grassland bearing rate of the accounting area according to the livestock stock column amount, the herbivorous wild animal existing amount and the grassland bearing capacity, and evaluating the grassland bearing condition according to the grassland bearing rate. The herbivorous wild animals are brought into the grassland bearing capacity accounting framework, the herbivorous wild animal balance condition is more objectively reflected under the condition of comprehensively considering the feed intake of livestock and herbivorous wild animals, and a regulation and control tool is provided for animal husbandry scale management and control and natural protection dynamic management.

Description

technical field [0001] The invention relates to the field of ecological balance, in particular to a herbivorous wild animal-based method for evaluating the balance of grass and livestock. Background technique [0002] Overgrazing and overgrazing are the main human factors of grassland degradation, and the balance of grassland and livestock is an important goal of grassland management (VETTER, 2005; Li Qingfeng, 2011). Grass-livestock balance refers to the state in which the amount of forage provided by grassland and other means and the amount required by livestock reach a balance in a certain time and space. Forage-livestock balance accounting indicators include four aspects: forage production, livestock feed intake, grassland utilization rate, and livestock carrying capacity (Mai Xiaohu et al., 2013). Forage-livestock balance emphasizes the biofeedback mechanism between forage and animals. The core of regulation is the evaluation of carrying capacity, stocking rate and pas...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the defect that the existing herbivorous wild animals are not fully considered in the existing herbivorous wild animal balance assessment method, resulting in serious deviations in the assessment of the grassland bearing status, the present invention provides a herbivorous wild animal based herbivorous wild animal balance assessment method, the present invention By including herbivorous wild animals into the calculation framework of grassland carrying capacity, the grassland carrying capacity can be calculated more scientifically under the condition of comprehensively considering the feed intake of livestock and herbivorous wild animals
