%X Ecological structure and function of 5 optimized models in newly built orchard in uncultivated slopping field are analyzed.The results show that organic matter increases by 5%-20%,total N increases by 7% ~40%,total P increases by 8%-70% and total K increases by 15%-80% every year.Good patterns in water and soil retaining are peanut-autumn soybean,spring soybean-autumn soybean,tomato-chinese cabbage,and cayenne-tomato,the soil average erosion module and runoff amount decrease respectively by 44.19%,38.24%,39.52%,37.56% and 22.40%,9.28%,24.11%,and 21.60% compared with CK.Cayenne-tomato is the highest in biomass,the average yearly is 100280 kg/hm2,the second is peanut-autumn soybean,the average yearly is 77030 kg/hm2.Tomato-chinese cabbage is the highest in productivity,the average yearly is 15390 kg/hm2,the second is cayenne-tomato,the average yearly is 13800 kg/hm2.Efficiency of energy introjection in order is cayenne-tomato,peanut-autumn soybean,tomato-chinese cabbage,spring soybean-autumn soybean,drought rice-red turnip.The averages of their total energy output/input ratios yearly are 2.96,2.08,2.01,2.00,and 0.96.
