It was on the road that how to quantify the scale of varieties of cultivate type and kinds of livestock and poultry into an one element index system.The mass of regional raising was hardly relate with risk assessment,because that was described usually in word but not number.So that brought into confusion in macroscopic management.This article put forward a new Animal Relative Crowd Index(ARCI)based on the quantity of dung.Three index values ARCA, ARCL and ARCH were used to quantify the relative density,relative density level,and unit density of livestock and poultry cultivation.And so constructed an comprehensive quantify and evaluate system about regional relative density of livestock and poultry cultivation.Took statistical datas of Chengdu City of 2015 as example,analysed by ARCI.The resuts showed that standard type was slaughter rate of hogs;ARCA code was 67.86%,raising density and corresponding environmental stress in unit area was 67.86%,the main reason was dung;ARCL code was 3,raising density was three level,senior and middle level,corresponding environmental stress scope was 64% ~80%;unit relative density of raising relative ARCH code was 28.66 head per hectare;total raising scale of Chengdu in 2015 was 14 493 247 head by slaughter rate of hogs.
