種(zhong)(zhong)植業與養(yang)(yang)(yang)(yang)(yang)殖業缺乏協調(diao)規(gui)劃(hua)導(dao)致(zhi)“種(zhong)(zhong)養(yang)(yang)(yang)(yang)(yang)分離(li)”日趨明顯，由此影響了種(zhong)(zhong)養(yang)(yang)(yang)(yang)(yang)系統間物質循(xun)環(huan)利用(yong)(yong)過程，導(dao)致(zhi)畜(chu)禽糞(fen)便(bian)過量(liang)(liang)對生態環(huan)境(jing)造成極大危害(hai)。為(wei)此，從種(zhong)(zhong)養(yang)(yang)(yang)(yang)(yang)系統間物質循(xun)環(huan)與農(nong)業污染(ran)之(zhi)間的(de)(de)內在(zai)聯(lian)系出(chu)(chu)發，提出(chu)(chu)“種(zhong)(zhong)養(yang)(yang)(yang)(yang)(yang)平衡(heng)”發展(zhan)模(mo)(mo)式(shi)，分別(bie)從以種(zhong)(zhong)定(ding)養(yang)(yang)(yang)(yang)(yang)、以養(yang)(yang)(yang)(yang)(yang)促(cu)種(zhong)(zhong)的(de)(de)角度探討了種(zhong)(zhong)植業與養(yang)(yang)(yang)(yang)(yang)殖業平衡(heng)發展(zhan)模(mo)(mo)式(shi)的(de)(de)實現途徑：“以種(zhong)(zhong)定(ding)養(yang)(yang)(yang)(yang)(yang)”是(shi)(shi)從種(zhong)(zhong)養(yang)(yang)(yang)(yang)(yang)系統物質循(xun)環(huan)的(de)(de)角度合(he)理(li)規(gui)劃(hua)養(yang)(yang)(yang)(yang)(yang)殖規(gui)模(mo)(mo)，防止畜(chu)禽糞(fen)便(bian)過量(liang)(liang)產出(chu)(chu)增(zeng)加環(huan)境(jing)壓力；“以養(yang)(yang)(yang)(yang)(yang)促(cu)種(zhong)(zhong)”是(shi)(shi)通(tong)過畜(chu)禽糞(fen)便(bian)無害(hai)化(hua)處(chu)理(li)和(he)科學合(he)理(li)地還田利用(yong)(yong)等(deng)手段，降低畜(chu)禽糞(fen)便(bian)資(zi)源化(hua)的(de)(de)環(huan)境(jing)風險。通(tong)過建立“以種(zhong)(zhong)定(ding)養(yang)(yang)(yang)(yang)(yang)”、“以養(yang)(yang)(yang)(yang)(yang)促(cu)種(zhong)(zhong)”的(de)(de)農(nong)業生產模(mo)(mo)式(shi)，實現廢(fei)棄(qi)物高效循(xun)環(huan)利用(yong)(yong)，降低環(huan)境(jing)污染(ran)風險，從而(er)緩(huan)解農(nong)業污染(ran)減(jian)排壓力。
