农田林网经营模式效益评价

(1) 几种收益指数:

1)      农作物增产收益(CY):

式中,CYjt为第t年底j种林网的农作物增产收益;为第t年底j种林网防护效果的夏熟作物增产量;CPj为第j种林网夏熟作物的价格;为第t年底j种林网防护效果的秋熟作物增产量;APj为第j种林网秋熟作物的价格。

2)      薪材效益(WY):

式中,WYjt为第t年底j种林网的新材收益;BWjt,SWjt,TWjt为第t年底j种林网林木枝、皮、干的干重;WQjj种林网的新材热值;CQiCPi分别为第i种树种折合标准煤的热值和价格。

3)      商品材收益(TY

             

式中,TYjt为第t年底j种林网的商品材收益;Vjt为第t年底j种林网的木材蓄积量;TPj为第j种林网的商品材价格。

4)      果品收益(FY

            

式中,FYjt为第t年底j种林网的果品收益;FWjt为第t年第j种林网的果品产量;FPjt为第t年底j种林网的果品价格。
