Realization of visualization software for yak body weight calculation (VBWC) in three-river headwaters region based on body size

摘要

Three-River Headwaters Region is the typical alpine grassland characteristics of complex ecosystems, animal husbandry production to yak grazing as the main industry. The traditional way of grazing in the alpine animal husbandry has been unable to meet the requirements of the wisdom pasture. How to use the computer technology to change the traditional grazing program is an urgent problem to be solved. The body weight data of yak were substituted into the linear regression equation by weight visualization software to obtain the weight of yak. Using Graham's scan method and Jarvis march method were used to solve the weight of the yak population structure in Three-River Headwaters Region. Combined with the characteristics of yak in the Three-River Headwaters Region proposed interval-qualified Graham's scan. The VBWC contains four languages for the input system and the yak body weight changes generated by the graphical output system. VBWC provides reference for herdsmen's application and scientific research in Three-River Headwaters Region.
