摘　　要：通过样地测设,研究了不同梯田坡向对地堰种植花椒、金银花、花生生长量、产量、经济效益的影响关系。研究表明:由于梯田坡向不同,梯田地堰经济林生长的环境迥异,树冠对光能的利用情况差异明显,从而造成了其生长量、产量、经济效益的差异,并对农作物产生了明显"胁地"效应。Through the sample plot test, the differences in terrace slopes have an great effect on the growth, yield and economic benefits of Chinese prickly ash, honeysuckle and peanut. Research shows that： due to the different slope of terrace field, terrace barrier economic forest grows in different environment, the differences of light energy utilization made by canopy are obvious, thus, the differences in the growth ,yield ,economic benefits and the crops produced shade effect obviously.
