江苏环境资源与第一性生产潜力的估算

Study on Environmental Resources and the Potential Primary Productivity of Jiangsu Province.

本文采用Y=F(Q)·F(R)·F(Y)·F(W)·F(S)及其分部公式,计算了江苏省主要农作物、森林和水生植被的潜在生产力。计算表明,麦类的潜力为2.14×10~3～6.08×10~3kJ/m^2·a,水稻的潜力为4.38×10~3～14.2×10~3kJ/m^2·a,春玉米的潜力为8.46×10～20.51×10~3kJ/m^2·a,森林植被为14.5×10~3～54.2×10~3kJ/m^2·a,水生植被为2.67×10~3～5.77×10~3kJ/m^2·a。

According to Y=F(Q)·F(R)·F(T)·F(W)·F(S)and its detailed equations,potential net productivity of major crops,forests and freshwater vegetation in Jiangsu province were computed. The result shows that potential productivity of wheats is 2.14×10~3-6.08×10~3kJ/m^2·a,potential produc- tivity of rices is 4.38×10~3-14.2×10~3kJ/m^2·a,potential productivity of spring corn is 8.46×10~3-20.5× 10~3kJ/m^2·a,potential productivity of forests is 14.5×10~3-54.2×10~3kJ/m^2·a and potential productivity of freshwater vegetation is 2.67×10~3-5.77×10~3kJ/m^2·a.
