Embodiment

[0060] A 12,000-mu area of ​​a typical grassland in Xilin Gol League, Inner Mongolia Autonomous Region was taken as the object to calculate the balance system of water, grass and livestock.

[0061] A 12,000-mu area of ​​a typical grassland in Xilin Gol League, Inner Mongolia Autonomous Region was taken as an object to calculate the water and grass balance system. The balance formula of aquatic plants is:

[0062] P e + W max = Σ i = 1 n E T i · m i - - - ( 1 )

[0063] Use formula (2) to calculate the effective precipitation:

[0064] P e =α·P (2)

[0065] The effective precipitation is calculated for the regional wet year...

Abstract

The invention discloses a water-grass-livestock balancing system comprising a water-grass balancing sub-system and a grass-livestock sub-system. The water-grass balancing sub-system determines a plantation structure and area for irrigation of a fodder grass land each year according to effective precipitation and maximum irrigation water, so grass is determined by water; and the grass-livestock balancing sub-system determines livestock breeding numbers each year according to grass output of the native pasture and artificial fodder grass land, so livestock numbers are determined by grass. The water-grass-livestock balancing system is divided into a water-grass and grass-livestock balancing sub-systems, so a mode of grass defined by water, and livestock defined by grass is formed; complicated work is simplified; and balance calculation is conducted to the two sub-systems individually.

Description

technical field [0001] The invention relates to the field of ecological balance, in particular to a water, grass and livestock balance system. Background technique [0002] The balance system of water, grass and livestock is a composite ecosystem, and the elements that make up this system include: development and utilization of water resources, grassland productivity, livestock quantity and herd structure, etc. They not only exist as a single system, but also play their specific functions in the overall large system. [0003] The traditional linear and nonlinear objective function method can be used to calculate the balance system of water, grass and livestock, but it involves many influencing factors, it is difficult to obtain parameters and the accuracy is difficult to guarantee, and the practical application is difficult. Contents of the invention [0004] In order to solve the above problems, the present invention provides a balance system for aquatic plants and lives...
