On the basis of the discussion of the ecological rehabilitation on subsidence land of coal extraction , the land structures of nourishment , plane and perpendicularity on subsidence area of coal extraction are differently designed . on nutritive structure green crops are mainly common crops , green vegetables , green forage crops and acquatic creatures . on plane structure the center of the subsidence land of coal extraction can be used as fish culture in net cage , the periphery can be established as fish pool and economic crops in water , and the outmost layer can be used as high - yield field , vegetable shed , domestic animal breeding area and fruit - bearing forest . on vertical structure the deepwater area can be established as fish pool and economic crops in water , and the uppermost layer can be developed as acquatic and semi - acquatic crops or dry farming crops 在討論采煤塌陷地生態(tài)復(fù)墾的基礎(chǔ)上,對新泰市采煤塌陷區(qū)生態(tài)復(fù)墾用地的營養(yǎng)結(jié)構(gòu)、平面結(jié)構(gòu)和垂直結(jié)構(gòu)進(jìn)行了優(yōu)化設(shè)計(jì).在營養(yǎng)結(jié)構(gòu)上,綠色作物主要是農(nóng)作物、蔬菜、飼料及水生生物.在平面結(jié)構(gòu)上,在塌陷的中心地帶實(shí)施網(wǎng)箱養(yǎng)魚,外圍區(qū)建立精養(yǎng)漁塘和水生經(jīng)濟(jì)作物,最外層生態(tài)復(fù)墾為高產(chǎn)農(nóng)田、蔬菜大棚、畜禽養(yǎng)殖區(qū)和林果地.在垂直結(jié)構(gòu)上,在積水區(qū)建立精養(yǎng)漁塘和水生經(jīng)濟(jì)作物,最上層則發(fā)展水生、半水生及旱作綠色經(jīng)濟(jì)作物
