在湖北西部清江流域生活的土家族,由于其闭塞和险恶的自然环境,使之保存了丰富的原生态文化资源,其中又以饮食文化最具特色,本文对此作了全面的探讨和清理,并提出加强保护和开发这种独特而又丰厚的文化资源,以维护文化的多样性。

The average depth of the 15 surveyed sample plots is(8.2 cm),and the maximum,13.7 cm,the minimum,1.5 cm,with 10 times differences between these two values.The undecomposed component in the withered litters of moss is relative more,accounting for 42.8%,and semi-decomposed and decomposed one is less,accounting for 23.8% and 33.4%,respectively.

结果表明,试验流域苔藓枯落物层分布与组成存在明显差异,15个样地平均厚度8.2 cm,厚度最大达13.7 cm,最薄仅1.5 cm,相差近10倍;苔藓枯落物中未分解成分较多,占总量的42.8%;半分解和已分解成分较少,分别占23.8%和33.4%。

The article analyzes and proves plan and measure under the new cercumstances development and existing problems in Xinjiang water resources development in the Western development,we must firmly establish the idea of the whole-valley balance,well do water resources development Plan,groundwater,surface water overall distritution,joint expoitation,especially whole develop unfully utilized groundwater resources.

摘 要:探讨我区水资源开发中存在的有关问题,对新形势下可能的发展、应对的方案及措施进行分析论证。在西部大开发中,我区要做到水资源可持续开发与利用,必须牢固树立全流域平衡的观念,做好水资源开发规划,地下水、地表水统筹分配,联合开发,尤其要大力开发还未充分利用的地下水。

Using MODIS data, the parameters of the modified SCS model were determined, and the model was applied to the daily runoff simulation. It made an attempt for predictions in ungauged basins.

结合MODIS遥感数据确定改进的SCS日模型参数,进行流域径流模拟,为开展无资料地区的水文预报进行了一定的尝试。

Therefore, the development trends are: to establish the dynamic NSP pollutant transport and transformation model which can be applied easily to ordinary natural watershed; to study the estimation methods of NSP load and model parameterized in terms of geomorphic parameters (Horton's numbers) for ungauged watershed.

因此,发展趋势为:第一,建立以污染物迁移转化机理为基础的、适合于野外流域和便于推广应用的非点源污染负荷模型;第二,研究无资料地区的非点源污染负荷估算方法与模型参数估计途径。

On the base of reviewing the development of NSP models, some deficiencies of existent models are analysed and listed as follows: most models can be applied only to very small watershed; mechanism models involve too many parameters which can not be calibrated properly by limited data; amoung practical models, empirical models are much more common than mechanism models; most models are focus on the conservative soluble pollutants rather than non-conservative and particulate pollutants; almost all models rely highly on the measured data, and there are fewer studies about the load estimation for ungauged areas.

本文在评述非点源污染模型研究进展的基础上,分析了现有模型的不足,主要有:大多数模型只能适应于很小的流域面积;机理类模型参数过多,率定困难,应用效果不理想;实用模型中,经验类模型多,机理类模型少;对保守性的液态污染物研究得较多,对非保守性和固态污染物研究得较少;各类模型均高度依赖于实测资料,无资料地区的模型或预测方法研究得很少。

搜集、分析了贵州省有代表性的17个小流域土壤侵蚀和土壤侵蚀影响因子的相互关系,总结出了贵州山区土壤侵蚀的非结构性知识,为进行基于非结构性知识发现的土壤侵蚀信息提取初级和高级方式研究奠定了知识基础。

Liu's mission being not to stop and fight, but to get into the Yangtze Valley some 200 miles away, his attack, unsupported by follow-up columns and unsupplied from the rear, had somewhat the character of a parachute drop or a cavalry raid deep into enemy territory.

刘的任务不是在一个地方停下来作战,而是要长驱二百多英里,把部队开到深入长江流域的地方去。

This paper introduced the concept of information entropy for analyzing the influence of DEM resolution on topographic characteristics(slope,upslope area per unit contour length and topographic index) calculation.

本文以褒河流域为例,引入信息熵的概念量化分析了 DEM分辨率对地形特征(坡度、单宽上坡集水面积和地形指数)计算的影响,发现随着 DEM分辨率的降低,计算得到的坡度值偏小,单宽上坡集水面积值偏大,从而导致地形指数计算值偏大。
