摘要:
总结了新中国成立60年(nian)来(lai)我国草(cao)(cao)原(yuan)畜(chu)牧(mu)(mu)业(ye)的发(fa)(fa)(fa)展(zhan)情况,指出(chu)我国已经(jing)探索出(chu)一(yi)(yi)条适合中国特色的草(cao)(cao)原(yuan)畜(chu)牧(mu)(mu)业(ye)发(fa)(fa)(fa)展(zhan)道路。草(cao)(cao)原(yuan)畜(chu)牧(mu)(mu)业(ye)生产水平(ping)在(zai)不(bu)断(duan)提高,如牧(mu)(mu)区每年(nian)向农区提供育肥用牛羊达(da)到3 000多(duo)万头(tou);草(cao)(cao)原(yuan)畜(chu)牧(mu)(mu)业(ye)生产结构(gou)不(bu)断(duan)优化;经(jing)营模式不(bu)断(duan)转变,产、加、销一(yi)(yi)体(ti)化格局正(zheng)在(zai)加快形成;草(cao)(cao)原(yuan)畜(chu)牧(mu)(mu)业(ye)发(fa)(fa)(fa)展(zhan)基础日益(yi)牢(lao)固,仅2000年(nian)以来(lai),国家(jia)对(dui)(dui)(dui)草(cao)(cao)原(yuan)保护(hu)建设(she)的投(tou)入(ru)已超过200亿元;草(cao)(cao)原(yuan)畜(chu)牧(mu)(mu)业(ye)对(dui)(dui)(dui)生态安(an)全和经(jing)济发(fa)(fa)(fa)展(zhan)发(fa)(fa)(fa)挥了重(zhong)要作用,局部地区生态环境已得到明显改(gai)善。但是(shi),受草(cao)(cao)原(yuan)生态安(an)全问题,生猪型畜(chu)牧(mu)(mu)业(ye)生产特点和草(cao)(cao)原(yuan)地区自身发(fa)(fa)(fa)展(zhan)能力等因素的制约(yue),草(cao)(cao)原(yuan)畜(chu)牧(mu)(mu)业(ye)发(fa)(fa)(fa)展(zhan)还面临(lin)许(xu)多(duo)突(tu)出(chu)矛盾和艰巨挑战。因此,应该积极应对(dui)(dui)(dui)客(ke)观(guan)矛盾和问题,牢(lao)牢(lao)把(ba)握当前发(fa)(fa)(fa)展(zhan)的有利机遇,进一(yi)(yi)步推(tui)进草(cao)(cao)原(yuan)畜(chu)牧(mu)(mu)业(ye)发(fa)(fa)(fa)展(zhan)。
