A Study On Ecological Agriculture With Farming Characteristics Of Western Part, Heilongjiang Province

The agriculture development has been a new stage in China, and a deep change happened to its development target, functional task, external and internal environment. So, it is very stringent to construct ecological agriculture and some special ecological agriculture mode occurred in some place and all over the world. In this paper, the concept of ecological agriculture was put forward based on existing data according to the practical condition from the farmland in the west of Heilongjiang Province, and the main content of ecological agriculture was illustrated, and the system table for the ecological agriculture was formed. The ecological agriculture should be dynamic, developmental, highly effective, and sustaining; it also should develop with the society, and develop with environment hormonally, and stress the best synthesis benefit of economy, society and environment.Heshan farm of Nongken Jiusan substation in Heilongjiang Province is the typical farm in the west of Heilongjiang Province. It is representative in environmental condition, social economy condition and soil use structure. This paper discussed the method of construction partition for ecological and the chosen for ecological developing mode. One of the innovations was that the gray system mathematical model was introduced, based on it, the ecological agriculture with farming characteristics region was partitioned using qualitative and quantitative analysis method. Using this method could increase the theoretics, veracity and maneuverability. Another innovation was that the layered designing mode was utilized, which change the method of single layer designing mode used in the past. This method helped to develop clearly for the ecological agriculture on macroscopical and microcosmic view.Water conservancy is the life line of agriculture and the sustainable use of water resources is the important guarantee for ecological agriculture construction. So, the high efficient use of water resources in the ecological in the agriculture is necessary. This paper discussed the principle for agricultural water resources utilization and its countermeasure for water loss and soil erosion and seasonal water depletion district, based on actual data from the west farm in Heilongjiang Province.Ecological agriculture should be system engineering in which multi-disciplinary and multi-domain corporate tightly. This system not only need hardware facility...
