摘要
由于土地资源的不断开发,新疆宜农后备土地资源的面积不断减少,土地开发条件越来越差,造成一些土地开发以后成为低产田或无灌溉水源而弃耕,使非常有限的土地开发资金浪费。为了使新疆宜农后备土地资源开发有计划、有重点、有目的、分阶段的顺利进行,更好的发挥新疆宜农后备土地资源开发的经济效益,必须研究清楚新疆现阶段宜农后备土地资源的数量、质量、与分布。以现阶段新疆宜农土地资源开发利用技术水平和农业生产技术水平及所产生的经济效益为基础,参照新疆水资源和土地开发资金,注重对生态环境的保护,兼顾农林牧业共同发展的方针,划分出新疆现阶段宜农后备土地资源。
Xinjiang is one of the important development regions of the land resources suiting for farming in China all along. It is planned to reclaim the wasteland suiting farming for 310 000hm2 in Xinjiang during the 'Ninth FiveYear Plan'. Along with the continuous reclamation of the wasteland, the area of the reserve resources of land suiting for farming is continuously reduced in Xinjiang, their reclaiming conditions are more and more poor, and some reclaimed land is become as the low-yield land or abandoned from cultivation, which results in a great waste of the very limited land reclaiming funds. The area, quality and distribution of the reserve resources of land suiting for farming in Xinjiang at present must be thoroughly researched so as to reclaim the wasteland suiting for farming in a planned way and make the ideal economic returns. In this paper, the reserve resources of land suiting for farming in Xinjiang at present is classified based on the technological level of wasteland reclamation and land use and of agricultural production, the water resources and the reclaiming funds, and great attention is paid to protection of the ecological environment and coordinative development of agriculture, forestry, and animal husbandry. Some new progresses are achieved in the paper: (1)On the aspect of the classification system: (a) partial aeolian sandy land is regarded as the resources of land suiting for farming; (b) the level land covered by the well-growing forests (mainly the popular diversifolia forests) is evaluated as the forest land only according to the situation of shortage of the forest resources and the requirement of the ecological environment protection; (c) the well-growing forage grasslands in grade one and two are evaluated as grasslands only. (2)The classification is divided into two steps: (a) the total reserve resources of land suiting for farming is firstly classified based on the internal conditions of land; (b) then the suitably-reclaimed reserve resources of land suiting for farming is classified based on the external conditions of land reclaimation.
