Most plants have fundamental capacities of capturing light energy and assimilating carbon, and their differences in resource acquisition, processing and investment have very great effects on the species composition and function of an ecosystem. It is widely accepted that leaf traits such as specific leaf area (SLA) and leaf nutrient contents are sensitive indicators of environmental conditions. The variation in SLA and leaf nutrient content and the relation between the two can reflect plant responses and adaptations to climatic and environmental conditions. The study was done to investigate the SLA and mineral nutrient contents of Chinese Caragana (Caragana korshinlii Kom.) in the Loess Plateau region suffering both wind and water erosions in its main growing months in order to find out the patterns whereby the SLA and mineral nutrient contents of Chinese Caragana vary with different habitats and growing months. The results show that of Chinese Caragana, the SLA little differed among different habitats (P> 0.05). In different habitats, the SLA of Chinese Caragana varied identically and corresponded with its leaf growths. In this study, the SLA of Caraganas varied much so that Caraganas adapted itself to different habitats. On the north-facing slopes, the SLA were highest but the leaf N contents and light intensities were the lowest, and on the south-facing and half-south facing slopes the SLA were the lowest, but the leaf N content and light intensities were the highest. This was probably caused by different soil moisture of the different slopes. The leaf organic carbon contents ranged from 43.171% to 45512%, 42217% to 44.326%, 43.620% to 44.517% on the south-facing, half-south facing and north-facing slopes, respectively. The Leaf nitrogen (N) and potassium (K) totals differed among the different habitats, but differed significantly among the months. The Leaf phosphorus (P) contents differed significantly among the habitats and the growing months. In the different habitats, as the growing months alternated, the leaf N/P ratios varied significantly, but the C/P ratios varied little; and the C/N and C/K ratios did not significantly differed but all varies significantly as the growing months alternated. However, the mean N/P ratios in all habitats were higher than 16, indicating that in the area suffering both water and wind erosions the growth of Chinese Caragana was more susceptible to P constraint, which was mainly attributed to the lower soil P content that probably resulted from strong soil and water erosions occurring in the area. As the growing months alternated, the leaf N, P and K contents, the leaf C/N and C/P ratios varied significantly in the different habitats, and this was probably mainly due to the different nutrient requirements of the plant at the different growth stages, such as allocating more N to insoluble proteins to enhance cell wall resilience, and increasing leaf cell density to tolerate environmental stress. The higher the leaf organic carbon contents and N/P rations of Chinese Caragana were, the lower the leaf areas per unit mass, and as growing months alternated, the correlation between the leaf SLA and leaf C, N, P and K contents and the leaf C/N, C/P, C/K, N/P ratios varied little, but the roles of the correlation perform differently. Therefore, the leaf SLA of Caragana were the result jointly resulting from the actions of all the leaf nutrients in the different growing months. Consequently, the habitats and growing times were probably the important reasons for the variations in structural characteristics and nutrient composition, but the factors regulating leaf characteristics were more complex, Chinese Caragana had its own adaptation mechanisms to its habitats and growing months in respect to different nutrient elements.
