中文摘要	中亚地区土地资源开发与利用研究信息资料有限,研究深度无法满足亚欧内陆干旱区社会经济可持续发展的科学要求。采用欧空局(ESA)GlobCover 2 2005年的全球陆地覆盖数据集资料和世界粮农组织(FAO)统计资料,较为系统分析了1992-2009年中亚土地资源开发与利用及其变化趋势。研究表明:(1)中亚耕地面积及作物产量呈先迅速下降后缓慢上升的趋势,耕地面积由1992年的43.110~4 km~2(比例10.9%)下降到2000年的29.810~4 km~2(比例7.58%),然后上升至2009年的31.610~4 km~2(比例8.04%),但仍未恢复到1990年代初的水平;(2)林地与草地面积变化不明显,但草地载畜量变化显著。其中哈萨克斯坦2009年草地载畜量(6.2510~7标准羊单位)仅为1992年草地载畜量(9.9110~7标准羊单位)的63.1%;土库曼斯坦2009年草地载畜量为2.9610~7标准羊单位,是1992年草地载畜量(1.04*10~7标准羊单位)的3倍左右;乌兹别克斯坦、塔吉克斯坦和吉尔吉斯斯坦草地载畜量均有不同程度的增加;(3)中亚地区土地资源生产潜力巨大,但在土地利用过程中出现了农田土壤侵蚀、土壤盐渍化和过渡放牧等生态问题,如何有效治理与防治上述问题,对中亚地区土地资源可持续利用和生态保护具有重要意义。
英文摘要	The study on the development and utilization of land resources in Central Asia is instability, for the rea-son that the information is limited. Then, it is difficult to meet the relevant systemic research to fit the need about the socio-economic sustainable development of the Asia - Europe inland arid regions. Therefore, in this paper, the 2005’s global land cover dataset materials of ESA and the statistical data of FAO are used to study the development, utilization and the change tendency of the land resource in Central Asia during 1992 - 2009. The results indicate as follows:(1) The area of the farmland and the crop productivity decrease rapidly, and then increase slowly. The area of the farmland decreases from 43. 1 * 10~4 km~2 (10.9%) in 1992 to 29.8 * 10~4 km~2 (7.58%) in 2000, and then increases to 31.6 x 10~4 km~2(8.04%) in 2009 which is still far from the farmland area in 1992. Because of the breakup of the Soviet Union, a series of problem including the shortage of means of production, the destruction of the agricultural infrastructure and the market economy is still not established which had been caused the waste of land. After that, the independent of the states in Central Asia leads the recovery of the social economy and the area of farmland. (2) The areas of forest and grassland in Central Asia are varied little. However, the grassland grazing capacity has changed in large degree. In details: the grazing capacity of Kazakhstan has been decreased continually with the number 6.25 * 10~7 sheep in 2009 that is only accounts to 63.1% of the 9.91 * 10~7 sheep in 1992; on the contrary, the grazing capacity of Turkmenistan has been increasing from 1.04 * 10~7 sheep in 1992 to 2.96 * 10~7 sheep in 2009 that is triple of 1.04 * 107 sheep in 1992; the grazing capacity of Uzbekistan, Tajikistan and Kyrgyzstan increases at different degree, respectively. The privatization of pasture in the most of Central Asia and the damage of seasonal pasture contribute to the change of the grassland grazing capacity. (3) The potential productivity of the land resource is great in Central Asia. However, ecological problems such as soil erosion and soil-salinization of the farmland and pasture overgrazing, have been discovered in this area. In addition, the reasonable application of water resources in Central Asia has great important ecological significance and e-conomic value, especially in the arid land. But, as well know, the water resources are shortage and the distribution is not reasonable, and there are still some problems in the application of the water resources, such as, the waste of water, the pollution of water. As a result, there is a great problem for the countries in Central Asia that is how to solve and control the above issues efficiently has great effects on the sustainable development of the land resource and the protection of the ecology in Central Asia.
