This paper described the basic principle and recent advanes of the comprehensivemulti-storied and dimension agriculture. Meanwhile, this paper also disclassed therelationship of the stereo agriculture to raising resource utilization rate; enhancing to takerural surplus labor forces into employment partially, and maintaining the sustainabledevelopment of agricultural production.In this thesis, the comprehensive multi-storied and dimension planting agriculture inAncient River Channel in HeBei province was studied. In order to find patterns of thecomprehensive multi-storied and dimension planting agriculture with economics andenvironment in Ancient River Channel in HeBei province, sampling and analysis wereused to study the status of trends of nutrients accumulating, biomass, economics andoptimized analysis in Ancient River Channel in HeBei province.Through the analysis of fruit/herbal medicine complex system in Zhulong AncientRiver Channel and the pear/Tatar Rootrian Aste fertilizer experiments used D-311Bdesign plans. The data is indicated: Pear/aster tataricus compound system can improve thenutrient utilization rate, but the pear output is not significantly affected. The potassicfertilizer can not compose to experiment field limiting a factor, the best economy beingable to get aster tataricus applies fertilizer expecting that N: P2O5: K2O is115.8: 292.5:303.5, the best economic use of fertilizer can get for 16049.69 kg/hm2 of Tatar RootrianAste. The result of shionone indicated that the contents of shionone are not significantlyaffected at different fertilizer lever. The complex system is much higher than Shah assumessystem. Through the density experiments analysis of pear/ sapohshnikovia divaricata,pear/ Pinellia Tuber for harvest index and the value of index, it is known thatsapohshnikovia divaricata spacing maximum 40cm, 15cm x 3cm Pinellia Tuber highest.The higest economic effeciency is the pattern of Silk tree (4)/ Pinellia ternate in thepattern of froest/medical crops. The increased efficiency rate reached 120.6 qianyuan/hm2. Compared with wheat maize, Wheat/ Snakegourd Fruit intercropping isbeneficial result more 10.1~13.2 qian yuan/hm2 and the increased efficiency amounts to55.7%~64.7%. Maize/Arisaema consanguineum Schott intercropping is optimumcultivate proportion being 2: 6, be that the six lines of Arisaema consanguineum Schott andcultivating two row of maize.The economic efficiency is higest. The economic effeciency is analysis on the different patterns in Ancient River Channeland get the increased efficiency rate: compared with Wheat/maize the pattern of grain andoilbearing crop increases by 60.77%in Zhaoxian County in HuTuo Ancient river Channel;the pattern of grain and oilbearing crop and cotton increases by 64.1%in GuAn County inYongDing Ancient river Channel and the pattern of fruit and grain increases by 48.5%inYongqing County; the pattern of grain and Vegetables increases by 127.6%and the patternof cotton and oilbearing crop increases by 32.9%in Luan County in LuanHe Ancient riverChannel River; the pattern of grain and herbal medicine and guar increases by 68.75%inTang County in TangHe river Ancient Channel, Compared with the single-mode forcost-effectiveness.In this paper, an analysis of each mode is supporting three-dimensionalmulti-planting techniques for reference.Not only the complex systems can increase the land utilization rate, but also can beimproved energy efficiency and nutrient conversion rate. The data indicates compoundsystem efficiency of light energy utilization having improved 10%-20%, the increaseefficiency reaches 65%. LER is the land utilization value, LER calculating theinvestigation pattern data display most is 2.17 and lowest is 1.36. When LER>1.30 theland utilization rate is improved and land utilization value is increasesde.In this thesis, it optimized 60 patterns to be extended from investigating hundreds ofmodels of the comprehensive multi-storied and dimension planting agriculture in AncientRiver Channel in HeBei province. The pattern has the higher economic efficiency, theecology benefit and the social efficiency. According to the target and the weightappraisalmethods, the conclusion is obtained.
