| 摘 要： | 我国沙漠(含半干旱区沙地)、戈壁面积广阔,集中分布于北方温带、暖温带区域,是生态环境十分脆弱而自然資源相对富集的区域,极需有一个揭示沙漠、戈壁地域分异規律,反映沙漠、戈壁区生态地理特征的地理区划,以满足国家生态建设和资源开发的需求。直到目前我国还没有一个体系完整的这一区划。文中从揭示沙漠、戈壁地理分异規律,为生态建设服务目的出发,选择地域系统指标、气候水热指标和生态景覌指标,将我国沙漠、戈壁地域按3级体系划分:I级区(区)8个,II级区(亚区)31个,其下再按区域生态景观进行第III级(子亚区)的划分,并对第I级与第II级区的基本特征进行阐述。

| Abstract: | Covering a vast area of China and mainly distributed in the northern temperate zone and warm temperate zone,sandy and stony deserts are ecologically fragile but resources-rich land types.An eco-geographical regionalization of the distributional region of sandy and stony deserts in China is highly in need to reveal the differentiation and to reflect the eco-geographical features of sandy and stony deserts.For revealing the geographic differentiation law of sandy and stony deserts and facilitating ecological construction in the region,some indicators regarding the regional system,climatic hydrothermal conditions and ecological landscape were selected.The region was divided at three levels,including 8 first-level areas and 31 second-level areas,and some third-level areas according to regional ecological landscape.The basic characteristics of the first-level and second-level areas were described in detail. |
