Abstract: For the purpose of making certain the genetic resources and characteristics of Southwest horse,by means of local investigation,network technology and SPSS,I come to the conclution below:The amount of Southwest horse on hand is 21911 millions,the percentage in our country is 40146 %;The body size of Dali horse,Wumeng horse,Wenshan horse,Baise horse,Jianchang horse and Guizhou horse being differentiated from Southwest horse enlarge gradually from south to north and east to west;The physical structure of Southwest horse is compact and square approximatively.To take male horse for an example,its height,length,circumference and circumference of cannon bone respectively was (115119 ±7110) cm,(114111 ±8129) cm,(132122 ±9194) cm and (15117 ±1. 15) cm.The density - independent factors were taken into account and annual frost-free period,precipitation,sunshine hours,the average temperature have powerful effect to physical measure of Southwest horse,such as heightatwithers,they might play a leading role in the formation of different ecotype horses.The main factors of influencing the abundance distribution were agricultural machinery per capita,population density,administrative district ratio,and so on.
