CMIP6 is the sixth climate model comparison plan organized by the World Climate Research Program (WCRP). Original data from https://www.wcrp-climate.org/wgcm-cmip/wgcm-cmip6 。 This dataset contains four SSP scenarios of Scenario MIP in CMIP6. (1) SSP126: Upgrade of RCP2.6 scenario based on SSP1 (low forcing scenario) (radiation forcing will reach 2.6W/m2 in 2100). (2) SSP245: Upgrade of RCP4.5 scenario based on SSP2 (moderate forcing scenario) (radiation forcing will reach 4.5 W/m2 in 2100). (3) SSP370: New RCP7.0 emission path based on SSP3 (medium forcing scenario) (radiation forcing will reach 7.0 W/m2 in 2100). (4) SSP585: Upgrade the RCP8.5 scenario based on SSP5 (high forcing scenario) (SSP585 is the only SSP scenario that can make the radiation forcing reach 8.5 W/m2 in 2100). Using GRU data to correct the post-processing deviation of the original CMIP data, the post-processing data set of monthly precipitation (pr) and temperature (tas) estimates from 2046-2065 was obtained, with a reference period of 1985-2014.

A total of two types of seismic waves are used as input in the test, one type is sinel wave; the other type is natural wave, and the natural wave is adopted from Wenchuan Maoxian wave. The sine wave amplitude and frequency are unique, so it can be used to study the influence of ground motion parameters on the dynamic response of slopes. By comparing the dynamic response of slopes under the action of sine waves with different frequencies and amplitudes, the influence of the input seismic wave parameters on the dynamic response of rock slopes is investigated; the natural waves are selected from the bedrock seismic waves recorded at the Maoxian station. The seismic wave input is loaded in a step-by-step manner, firstly loading the sine wave with low amplitude, and then loading the Wenchuan Maoxian wave with 0.1g increase, and after each loading, white noise is carried out to analyze the natural characteristics of the slope. After each loading was completed, 10 minutes were spent to take pictures and observe the damage of the slope.

During the development of debris flow monitoring microwave radar prototype, a series of demonstration applications were carried out in tianmogou, Bomi County, Nyingchi Prefecture, Tibet Autonomous Region. The test alarm data and application alarm data information in the demonstration application were reported and recorded through the multi-mode communication unit. This record gives the report records during the test and application. The data is the original log records exported from the background database of the control center, which are listed in Excel table according to the display of the control center, so as to improve its readability. Because the debris flow microwave radar is a result oriented monitoring, that is, its monitoring results directly give whether there is debris flow, rather than the relevant conditions of debris flow. Therefore, this data is mainly used to determine the target recognition ability in the research and development process of debris flow monitoring microwave radar. The data can be used as a reference for the development of debris flow microwave radar.

The Wuyu Basin is bounded by the Gangdese Mountains to the north and the Yarlung Tsangpo River to the south, and is a representative basin to study the Cenozoic tectonism of the southern Tibet. The sedimentary strata in the Wuyu Basin include the Paleocene-Eocene Linzizong Group volcanics and the Oligocene Rigongla Formation (Fm.) volcanics, the Miocene lacustrine sediments of the Mangxiang Fm. and Laiqing Fm. volcanics, the late Miocene-Pliocene Wuyu Fm., and the Pleistocene Dazi Fm. Five sandstone samples from the Mangxiang Fm., Wuyu Fm. and Dazi Fm. and one modern Wuyu reiver sand sample were collected for detrital zircon U-Pb dating using the LA-ICP-MS method. Detrital zircon U-Pb ages in the Mangxiang Fm. show a large cluster at 45-80 Ma; those in the Wuyu Fm. show a large cluster at 8-15 Ma and a subsidiary cluster at 45-70 Ma; those in the Dazi Fm. show three large clusters at 45-65 Ma, 105-150 Ma and 167-238 Ma; and those in modern Wuyu river show a large cluster at 8-15 Ma and a subsidiary cluster at 45-65 Ma (Figure 1). Late Cretaceous-early Eocene zircons in all samples are consistent with the most prominent stage of magmatism of the Gangdese Mountains; the 8-15 Ma zircons in the Wuyu Fm. and modern Wuyu river are consistent with the magmatism of the Laiqing Fm.; and the Triassic-Jurassic zircons in the Dazi Fm. are consistent with the magmatism of the central Lhasa terrane. The results of detrital zircon U-Pb ages and sedimentary facies analyses in the Wuyu Basin indicate that the southern Tibetan Plateau suffered multi-stage tectonism-magmatism since the India-Asia collision: (1) Paleogene Linzizong Group-Rigongla Fm. volcanics; (2) tectonism-magmatism at ~15 Ma ended the lacustrine sediments of the Mangxiang Fm. and resulted in volcanism of the Laiqing Fm.; (3) tectonism at ~8 Ma resulted in the volcanic rocks of the Laiqing Fm. becoming one of the main provenances for the overlying Wuyu Fm.; (4) the Wuyu Basin formed braided river and received sediments from the central Lhasa terrane to its north at ~2.5 Ma. The geomorphic pattern of the southern Tibet has gradually formed since the Quaternary.

The data includes ecological policy documents after 1979, involving laws, regulations, terms and schemes on Ecological Governance and ecological management at the national and local government levels. The data combed the evolution process of the country in ecological and environmental governance, as well as the environmental strategies established in different development periods. The research group collected various documents of ecological policies on the government's official website and local yearbooks every year from 2018 to 2021. In order to ensure the relative integrity and pertinence of the data, this study sorted and selected the policy texts according to the following principles: ① the main sources of policies are the government's official website and its subordinate departments; ② Documents in line with ecological policies; ③ Select laws and regulations, plans, opinions, methods, detailed rules, regulations, announcements, notices, resolutions and other documents reflecting ecological environment policies. Construct the categories of the policy documents studied, that is, determine the perspective of analyzing the policy text, and define the primary and secondary categories, so that the chief coder and sub coder can understand it uniformly; ② Code the policies one by one after preparing the coding table according to the main category, that is, after carefully reading the policy content, if its content meets the analysis dimension required by the category construction table, fill its code into the coding table; ③ The data of this study is based on the official website and field policy research, which can effectively distinguish the contents of categories involved in the policy text. Therefore, the content analysis of this study has a good level of validity The innovation and evolution of policies change the impact of human activities on the environment to a certain extent, and the guidance and impact of ecological policies on environmentally vulnerable areas are more obvious. If we can fully grasp the dynamic change process of ecological policies and understand the evolution law of ecological policies, we can formulate ecological policies conducive to improving the environment, This paper studies the evolution law of Qilian mountain ecological policy issued since 1979 by using the content analysis method, in order to provide a scientific basis for the formulation of Qilian mountain ecological policy
