Surface water
Xinglongshan Nature Reserve River River Shuixi Shuixi is well developed，Good water quality。All belong to the Yellow River Water Covery。According to statistics，There are m88 reviewrivers with different sizes in the district、More than 30 Shuixi，Both originated from Ma Tuoshan and Xinglong Mountain，The total runoff of the year is 53.49 million m3。where，Xinglongxia、Water grinding mellasty runoff is large，The normal runoff is 0.1 ～ 0.23m3/s, the annual runoff exceeds 7 million m3/s，Water system distributed spread throughout the district，The flow can be roughly divided into two，West (West of Mado) flows to the northwest of Lanzhou City to remit into the Yellow River;，Finally, it also flows into the Yellow River。
The soil loss of the Loess Plateau is world -famous，The main source of the Yellow River sediment。Xinglongshan Nature Reserve is a stone mountain area，and the rainfall is higher than the average value of the Loess Plateau 1/3 to 1/2，It is precisely because of the relatively sufficient precipitation in the protected area，Forest growing lush，Good vegetation，To a large extent, the soil is protected，Soil and soil loss is greatly reduced，It is one of the least soil m88 best betting websiteloss in Gansu Province。
Analysis of the results according to part of the determination，Water quality in the protected area is generally good，Most of them belong to heavy carbonate type water，mineralization is 100 ～ 500mg/l，It is a low -mineralized freshwater resource。
groundwater
Meteorological conditions in the protected area are superior，Unique landform form，Special geological structure，Due to these factors, there is a large difference in spatial distribution and intensity.，Formed a complex hydrological conditions and various groundwater types in the protected area，It can be roughly divided into four situations according to its distribution rules: the loess and bottom base rock wind shell diving in the loess and hills，There are fewer exposure in the area; the base rock fissure diving in the naked mountain area of the base rock，is the most important diving type in the protected area，Both Ma Tuanshan and Xinglong Mountain are widely revealed; porosity diving in the rivers valley，m88 live casino gamesless distribution in the area，Only see it in Zhangjia Temple、Shangzhuang、Hongzhuanggou、Malian Beach、龛、Fracture water and pore water between the layers，This type of groundwater is exposed in the area less，Small distribution area。
Supply sources of the water in the protected area in the protected area mainly have atmospheric precipitation、Vertical seepage and river water of channel irrigation water、Betraine fissure water、The side supply of the ditch valley subtastic flow, etc.。The role of these supply factors in different areas is largely different，This is because geological and landform conditions have a certain control effect。
Ji Yan's exposed Middle Gao Mountain area，altitude，There is abundant rainfall，Bida fissure development，Provides extremely favorable factors for the supply of atmospheric precipitation，This is also the only way to get supplies for the fissure water of the base rock。Loess hill area，Single supply to accept atmospheric precipitation。Because M88 Online Live Casinothe loess is easily eroded and washed，Gully Valley system has a large distribution density，The floods formed by rainfall are mostly down in the form of temporary surface flow，Message into the Gully Valley becomes a surface runoff。River Valley and Gully Valley，Dive is distributed in the beach gravel pebble layer near the river bed，Due to the direct contact with the water diving and surface water，So，Surface water can become a direct supply source for rivers diving，At the same time, you can accept channel water、The gap valleys of the atmospheric precipitation and the side supply of the high -end land。
Xinglongshan Nature Reserve's groundwater is heavy carbonate、Calcium sulfate (HCO3+-SO42+-ca2+) type and heavy carbonate, calcium sulfate, magnesium (HCO3+-SO42+-ca2+-mg2+) Type，Weak alkaline。Various types of ions and various trace metal elements contained in water，It is suitable for the needs of the human body，For high -quality groundwater。
