| Abstract: |
| This paper analyzes the natural environment advantages and evaluates the structure rationality of agro-ecological system in Maowusu Sandland,with the purpose to discover the reasons of low system productivity and instable system structure.The results show that the principal restrictive factors are the exasperate ecological environment,the low benefit of scale production,the excessive stress of food supplies,the insufficient exploitation of characteristic industries,the lack of capital and techniques,the extrusive conflict between livestock and forage plants,and the poor production condition of stockbreeding.Whereas the natural environmental resources,such as sunlight,heat,water,wind energy and land,are advantageous to the sustaining development of agro-ecological system.In order to boost sandland agriculture effectively,it is necessary to regulate the planting and stockbreeding structure,to adopt the integrate models of agriculture-forestry or agriculture-stockbreeding,and to develop oasis agriculture,etc. |
