Study On Continuable Use Of Plantation Resource In Yongji City

From the fifties of last century, with the rapid development of modern industry, all kinds of natural resources are reduced quickly or near to end by people's unlimited exploitation. The atmosphere circumstance and small environment are badly polluted by the sewerage, exhaust gas and waste residue which are largely produced from industry production. At the same time, traditional agriculture is substituted by the modern one, in which quantities of fertilizer, pesticide and mechanical machines are widely used. This produces many problems, such as fertilizer and pesticide pollutions. Continuable development becomes people's focus problem. Always continues use of resource is the base of continuable development. Without always continues use of resource, without continuable development.Reasonably use of soil resource is the fundamentality of society economy's development. Continuable use of soil resource is the basic content of continuable development. Its kernel is to reasonably configure the soil resource and resolve the problem between people and soil which is produced by population increase and economy development. This should be under the precondition of plantation's protection.Continuable use of plantation resource is the substance base and precondition of society economy's continuable development. Its kernel is to guarantee that the soil resource could meet the demand of society development, which is under the condition of keeping and improving balance of nature. From the fundamental of continuable use of soil resource, on the base of investigate and analysis of plantation resource in Yongji city, through the evaluate of Yongji's plantation quality, the study reflects a series of problems, such as unreasonable structure of adding fertilizer, big area of plantation with middle or low production, ignoring change of salt and alkali plantation, etc. So, we should enhance the power of plantation and improve soil quality. Planting plans should be done according to local conditions. For plantations with middle or low production, systems of combination of seeding and maintenance should be improved. Salt and alkali plantation should be managed synthetically. Corresponding technological measures should be recommended according to main distributing areas and obstacle genes of different grades of plantations. These things are done to guarantee the continuable use of plantation resource.
