摘要
本文应用灰色局势决策的方法 ,把不同夏秋农作物组合作为事件 ,不同林木间距的搭配作为对策 ,对准北平原地区的农林复合生态系统类型进行选优。得出淮北平原地区的最优农林复合生态类型为 :春苔干—西瓜——杨树 (30 0 m× 30 0 m)类型 :优势农林复合类型有 :春苔干—红薯—泡桐 (10 0 m×10 0 m)类型、春苔干—秋蔬菜—杨树 (150 m× 150 m)类型。同时还得出淮北平原地区的农林复合系统类型的林木间距以 30 0 m× 30 0 m(杨树 )、10 0 m× 10 0 m(泡桐 )、150 m× 150 m(杨树 )为宜。
In this paper,Grey Decision Making was used to study the agroforestry ecosystem types,in which the summer-autumn crop combinations was regard as imcidents,and the matches of different row-spaces of tree as strategies.We conclude that spring vegetable-watermelon-poplar(300m×300m)type is the best dominant type,spring vegetable-sweet potato-paulownia(100m×100m)type and spring vegetable-autumn vegetable-poplar(150m×150m)type are the secong dominant types in Huaibei Plain of Anhui Province.Meanwhile,we also conclude that the proper row-spaces of tree for agroforestry ecosystem in Huaibei Plain are 300m×300m(poplar)、150m×150m(poplar)and 100m×100m(paulownia)。
