Cow as one organizational form of dairy cow breeding which promote dairy cow breeding toward scale, intensification district, dairy district develop quickly in the south recently. The following problems such as the shortage of cow green forage supply, the poor connection between green forage supply period and dairy district demand period become more serious. Therefore, establishing high-efficiency green forage supply system has become the active demand of cow's scale enterprises already.In the recent 20 years, there are less research of green forage system, the matured green forage supply system is mainly suitable for the quitted farmland that has kinds of grain or low output industrial crops, and is not suitable for developing the forage base of the intensive farmland in recent years. And intensive farmland forage base adopt different supply system, which need further completion. So this text on the basis of previous study, summarize green forage supply system on dairy farm of south agricultural district at present, and carry on overall and systematic analysis to compare all kinds of green forage, in order to offer consult for plan and relation of forage base of dairy district.At first on the basis of analyzing existent green forage supply system which is suitable for the forage base in dairy district of south agricultural district, indicate the problem of those systems. Secondly, optimizing those system with the aim of reducing the cost of system. Moreover, carry on quantitative analysis on the basis of reflecting the supply ability and supply cost of the green forage supply system, regarding character of the system as the index, compare various green forage supply system, give comprehensive appraisal to various green forage supply system by the way of gray relation analysis. On the basis of comprehensive appraisal, aiming at reducing green forage cost or improving green forage structure of the dairy district, optimize the existing structure of green forage supply system.We can draw some conclusion as follows:Firstly,The forage base which be establishde on certain kind of soil has special systerm.Secondly,The dairy district had better build a special forage production base.Thirdly,The type of pasture is annual cultivated grassland. Applying this systerm to the stable forage production base, the expendiute on green forages can be redunced by 10% in comparition wihe applying the other systerm.Fourthly,A certain systerm has its advateages to reduce the cost or to improve the quality of green forages in all kinds of systerms which can be applied to the intensive cultivation farmland. Fifthly, The characteristics of the forage base adopting the systerm which has the bigger grey coorelation degree includs different aspects as follows:First,it is a special forage production base; Second, the forage base be divided into three parts, the first part mostly provides grazing for dairy district in winter and spring,the second part mostly provides grazing in summer and fall,the third part provides ensile and succulent as supplement forage. The area of the first and the second parts occupy 80% area of forage base. In comparition wihe applying the other systerm,the expendiute of dairy district which applys above systerm to the stable forage production base on green forages can be redunced by 15%-20%.
