本数据集为2011-2020年黄土高塬沟壑区南小河沟流域杨家沟（治理）观测数据。杨家沟（治理沟）为南小河沟流域中的一条小支沟，2011~2014年流域面积为0.87km²，2015年以后流域面积1.01km²。杨家沟基本上按照“全面规划，集中治理，连续治理，沟坡兼治，治坡为主”及“工程措施与生物措施相结合”的治理方针，逐年连续治理。1952年只做了少部分塬面治理，1954年着重进行了沟道治理并开始封沟育草，1958年基本完成了适地治理。杨家沟径流站观测断面设在以生物措施为主进行水土保持治理的杨家沟主沟道，距杨家沟沟口公路270m处，主要观测流域以生物措施为主的治理效益及支沟的治理措施和方法。本数据集主要为杨家沟雨量站降水量观测数据及杨家沟径流站径流泥沙观测数据。

Yangjiagou (governance ditch) is a small branch ditch in Nanxiaohegou watershed, with a drainage area of 0.87km2 from 2011 to 2014 and 1.01km2 after 2015. Yangjiagou has been treated continuously year by year in accordance with the principles of \"comprehensive planning, centralized treatment, continuous treatment, ditch and slope treatment, mainly slope treatment\" and \"combination of engineering measures and biological measures\". In 1952, only a small part of the tableland was treated. In 1954, the gully was mainly treated and the gully was closed to cultivate grass. In 1958, the suitable land treatment was basically completed. The observation section of Yangjiagou runoff station is located in the main channel of Yangjiagou, which is mainly used for soil and water conservation, 270m away from the highway at the mouth of Yangjiagou. It mainly observes the control benefits of biological measures and the control measures and methods of branch ditches. This data set mainly includes precipitation observation data of Yangjiagou rainfall station and runoff and sediment observation data of Yangjiagou runoff station. </p>\n This table is compiled for all artificial or self recording rainfall observation stations that control the precipitation in the whole catchment area.\n
