摘要
用灰色关联分析方法，对青海省草地建设投资与草地产出作相关分析。结果表明：两者相关性较强，关联度系数γ＿（ｙ０１８）＝０．７１６８（畜牧业产值）和γ＿（ｙ０２８）＝０．７２４４（畜产品产量）；在草地建设分项投资中，与草地产出关联度最大的为灭鼠投资，分别为γ＿（ｙ０１５）＝０．９１６２（牧业产值）和γ＿（ｙ０２５）＝０．８８８５（畜产品产量），其次顺序为种草投资（γ＿（ｙ０１２）＝０．８２６６和γ＿（ｙ０２２）＝０．８１３１），草地围栏投资（γ＿（ｙ０１１）＝０．７４５８和γ＿（ｙ０２１）＝０．７５３４），改良草地投资（γ＿（ｙ０１３）＝０．７２００和γ＿（ｙ０２３）＝０．７２９５），灭虫投资（、。．６一０．６２９９和（γ＿（ｙ０２６）＝０．６２６０），畜棚投资（γ＿（ｙ０１４）＝０．５７５６和γ＿（ｙ０２４）＝０．５８０８），其它投资（γ＿（ｙ０１７）＝０．５８９６和γ＿（ｙ０２７）＝０．５９３８）。
A grey system analysis on the relationship between investment and output inpasture of Qinghai was carried. The results were that the coefficients of correlation were γ_(y018)=0.7168 (between Investment and output value) and γ_(y028)=0.7244 (between investment andoutput). Among the items of pasture construction, the most officient investment was onroudent control, which was highly correlated with both the output value and output (γ_(y015)=0.9162 and γ_(y025)=0.8885). And then followed by the investments on pasture establishing(γ_(y012)=0.8266 and γ_(y022)=0.8131), fencing (γ_(y011)=0.7458 and γ_(y021)=0.7534), improving (γ_(y013)=0.7200 and γ_(y023)=0.7295), pest controling (γ_(y014)=0.5756 and γ_(y024)=0.5808)and the rest in-vestments (γ_(y017)=0.5896 and γ_(y027)=0.5938).
