High-Efficient Use of Natural Resources and the Sustainable Development of Agriculture in Semiarid Areas of Shaanxi Province

Analysis the nature resources superiority and inferior of soil, light, heat and weather of Weibei dry plateau land. The light and heat is abundant. The rainfall is short and unevenly distributed. The dry disaster happens often, and soil fertility is distoirated. Natural resources use efficiency and land production level are low. From the long time study the high-efficiency use of natural resources model and sustainable argicultural development technology and method were studied. The result showed that the potential natural resources were exploited in Weibei dry plateau. The model of high-efficiency use of natural resources and main method of sustainable agricultural development were developed. This model can help to supply enough food, rise soil fertility, control soil and water erosion and environmental pollution, develop farmers economy, and reasonable use nature resources.
