| 英文摘要 | In the mountainous region of West Sichuan of China,’there are 7 kinds of basic household agrosystem including two ones,being single sector,i. e. nomadic and semi-nomadic systems,and 5 mixed agrosystems,having several sectors,i, e. graincrop dominant systems,industrial crop dominant system,herbal horticulture dominant system,woody horticulture dominant system and stock-breeding dominant system.Industrial crop dominant system and horticulture dominant system are operated mainly by the driving of the external force (commodity economyMn opening. The normal operating of these systems are seriously restricted by the conditions of market. Although the prospects of these systems are looking quite,their further developing will depend on the improving of conveyance circumstance and the processing conditions of the produce. Other systems are operated mainly by the driving of the internal force generated from self-supporting economy, being close or semi-open and their productive force are low. Their further developing will depend on readjusting the structure of systems.As for cultivated system, most household agrosystems are arranged as intercropping, inter-planting , multiple cropping and croprotation, a few acts as monoculture and swidden for fallow periods of 3-10 years. In pace with reducing of ≥10℃ accumlated temperature from 7,500℃to<3,000℃ ,the crops changes from 3 crops and 2 crops an year to 3 crops every two years to 1 crop an year. The herbal horticulture crops are 2 - 5 crops an year. There are 10 species and more of grain crops and about 10 vegetable species. In the whole of mountainous region of West Sichuan, industrial crops (mainly sugarcane)and horticulture plants (mainly apple and pear and vegetable)are usually monoculture in a successive section,a few of them are intercropped or in-terplanted with graincrop or planted as fance around the farmland. The livestock (mainly yak and sheep)in pastoral area are grazed on the natural grassland and only fceded a little concentrated feed such as highland barley and oats as well as salt in winter.The main direction and ways to improve and remake household agrosystems are: 1. to build the mixed agrosystems of multidominant sectors and the complex agrosystems by merging the producing, processing and selling of agricultural produce into an organic whole (2. to develop the coupling agrosystems between the farming area and stockbreeding area; 3. to spread the diversiform agroforestry systems;4. to carry the nomadic and semi-nomadic systems to settling down. |
