Xanthoceras sorbifolia Bunge, belongs to genus of Xanthoceras, family of sorbifolia, which is an unique woody oil plant in northern China, the ravines of the Loess Plateau is the most concentrated areas of its distribution. The adaptability of the plants, drought-tolerant, hi light, strong resistance, germination and strong, with a variety of development and utilization of value.With a conventional paraffin section method, Xanthoceras sorbifolia leaves which came from the town of Ulan Moron in Inner Mongolia Yijinhuoluo county had been a detailed observation and measurement, for eight kinds of sources of anatomical structures on the introduction for the study. Results showed that eight kinds of sources Xanthoceras sorbifolia leaves have a thick cuticle and cell walls of xanthoceras sorbifolia; mesophyll tissue differentiation significantly, have developed vascular tissue and vascular bundle sheath extension; pulse in the regional prevalence of Crystal cell and mucus cells.Select the total thickness of leaves, epidermal thickness, thickness of cuticle thickness, palisade and spongy tissue thickness, palisade and spongy tissue thickness ratio8indexes of drought-resistance, using ANOVA and LSD multiple comparisons, results showed that the sensitivity of Xanthoceras sorbifolia leaves drought resistance indexes of order size is: ratio of Palisade and sponge tissue thickness> spongy tissue thickness> horny under thickness. Leaves of drought-resistance of Xanthoceras sorbifolia order is:Arong county in Hulun Berer> Shandong Taian> town of Wulanmuluen> Kundu forest factory in Alukeer county> Wengniute county economic forest factory> Inner Mongolia agricultural University> Shuangjingzi forest factory in Aohan county> Dengkou, Arong county in Hulun Berer is the most strongest on drought-resistance of Xanthoceras sorbifolia,Dengkou is the weakest on drought resistance of Xanthoceras sorbifolia.
