The Study Of Water Network In Taishan Mountain Region

The study area of this article is mainly the region of the highest peak of Taishan Mountainand the nearby areas. The rough scope of the study area is east from Qingyang plat to Mata riverwatershed, west to Beisha river basin ,south to the line of southern of Taishan Mountain, northfrom Laogong village to Wande town. The study area can be divided into four drainage basins,the main watershed is the line from Jieshou town to Motian ridge to Qingyang plat.The articleused methods of the landform mathematical statistics of the drainage basins, the regressionanalysis of the river network data, the model parameters, and the other methods. Combined withfield survey, the author analyzed the morphological characteristics and the constitution of thewater network, the structure characteristic parameters of the network and the regional differencesin river development, and by the study of hydrological basin entropy and fractal dimension valueto judge the development stage of the water network.The author drawled the network according to the 1:50000 topographic map, extracted thenetwork data with the SPSS statistical software of mathematical, and processed the data using theGIS software. Then the author analyzed the network geomorphic characteristics parameters andmodel data by using the Horton’s law and other mathematical methods on the basis of the waternetwork infrastructure data. Through analycizing the dates,the author obtained the bifurcationratio range of the channels in Taishan Moutain is between 3.56 to 4.72; the length ratio range isbetween 0.97 to 2.51; the gradient ratio range is between 0.41 to 0.62; the area ratio range isbetween 1.78 to 5.35. But in the analysis of the network development we usually use the averageof the waterway at all levels, for example, the average branching ratio of the network is 4.29, theaverage length ratio is 2.41, the average gradient ratio is 0.5319, the average area ratio is 3.47,These average values reflect the network in the development of a strong prosperous period.The methods of drainage basin entropy and fractal dimension value are used in the analysisof drainage network development stage. The S value of the area - altitude integral of the overallstudy area obtained is 0.2677,the Hgvalue of geomorphic information entropy is 0.5857.According to the geographical significance reflected by the Hgvalue and the field observations itshows that the study area is in the stage of strong erosion so called the prime of life. Thencalculating their S values and Hgvalues of the four drainage basin areas in the study area, the S value of A basin is 0.3242,the Hgvalue of A basin is 0.4506; the S value of B basin is 0.3886, theHgvalue of B basin is 0.3338; the S value of C basin is 0.3955, the Hgvalue of C basin is 0.3231;the S value of D basin is 0.3671, the Hgvalue of D basin is 0.3692.The calculation of the fractal dimension values is using the method of the small boxescounting and the Horton’s laws. For the overall basin there are four values of fractal dimensionbased on four different methods, D0is 1.67,D1is 1.66,D2is 1.41 and D3is 2.34, in which the D3isnot as a judgment in accordance with the data anomalies. These data are representing differentgeographical significance, but in general, the data of the fractal dimension reflected the networkin the study area is in the stage of strong development.The fractal dimension values of four basinscan be calculated by using the method of the small boxes counting, the fractal dimension value ofA basin is 1.56, the fractal dimension value of B basin is 1.60,the fractal dimension value of Cbasin is 1.57,and the fractal dimension value of D basin is 1.62.The article war also contrasted and described the morphological difference in channeldevelopment.By analyzing the degree of network development in each basins shows that theerosion intensity in A and C basins is stronger than that in B, D basins, so the main watershed ofthe mountain will move to the north of the highest peak of Taishan Mountain.
