1) silhouette cover degree
2) total coverage
During a growing season,the total standing crops,total coverage and average heights of plant community,as well as soil physical and chemical characteristics in different grazing units ofstipa baicalensissteppe,Hulunbeir,were compared and analyzed.
3) foliage projective cover
In this paper,the seasonal and annual growth,foliage projective cover(FPC),evaporative coefficient(k),and net primary productivity(NPP) of 7 types of grasslands in North China were simulated by using a simple model based on well established ecological processes of water balance and climatic data collected at 460 sites over 40 years.
4) projection coverage of woody and herb layers
5) side cover
Design of hot runner injection mould with interconversion installation of moving half and fixed half for side cover;
According to the side cover structure characteristics of table model computer box, determined the progressive die and the single operation die.
