A Spatial and Temporal Analysis on NDVI in Urad Grassland During 2010-2019 Over Remote Sensing
MATEC Web of Conferences 336, 06029 (2021) https://doi.org/10.1051/matecconf/202133606029 CSCNS2020 A spatial and temporal analysis on NDVI in Urad grassland during 2010-2019 over remote sensing Yueying Zhang, Tiantian Liu, Yuxi Wang, Ming Zhang, and Yu Zheng* Henan Key Lab Spatial Infor. Appl. Eco-environmental Protection, Zhengzhou, China Abstract. The temporal-spatial dynamic variation of vegetation coverage from 2010 to 2019 in Urad Grassland, Inner Mongolia has been investigated by analysing on MODIS NDVI remote sensing products. This paper applies pixel dichotomy approach and linear regression trend analysis method to analyze the temporal and spatial evolution trend of vegetation coverage over the past 10 years. The average annual vegetation coverage showed a downward trend in general from 2010 to 2019. The vegetation distribution and change trend analysis provide a thorough and scientific reference for policymaking in environmental protection. 1 Introduction Urad Grassland as the study area in this work is located in the northern foot of Yinshan Mountain in China, with dry and windy winter and high proportion of wind erosion and desertification land. At present, over 70% grassland is seriously degraded, which is the main sand source of sandstorm and poses a threat to ecological security in North China [1][2]. Therefore, it is not only a typical ecological fragile zone which is very sensitive to global change, but also a critical ecological barrier in the mainland. Fortunately, government has constantly funded billions of RMB in Urad Grassland since 2003 to encourage in closing grassland, restoring vegetation, returning grazing to grassland and reducing population density [1]. -
Multi-Scale Analysis of Green Space for Human Settlement Sustainability in Urban Areas of the Inner Mongolia Plateau, China

However, a lack of multi-scale studies on intra-urban green space limits our knowledge of human settlement environments in this region. In this study, a synergistic methodology, including the main process of linear spectral decomposition, vegetation-soil-impervious surface area model, and artificial digital technology, was established to generate a multi-scale of green space (i.e., 15-m resolution intra-urban green components and 0.5-m resolution park region) and investigate multi-scale green space characteristics as well as its ecological service in 12 central cities of the Inner Mongolian Plateau. -

Dissertation Advisor: Ian Jared Miller Sakura Marcelle Christmas The Cartographic Steppe: Mapping Environment and Ethnicity in Japan’s Imperial Borderlands ABSTRACT This dissertation traces one of the origins of the autonomous region system in the People’s Republic of China to the Japanese imperial project by focusing on Inner Mongolia in the 1930s. Here, Japanese technocrats demarcated the borderlands through categories of ethnicity and livelihood. At the center of this endeavor was the perceived problem of nomadic decline: the loss of the region’s deep history of transhumance to Chinese agricultural expansion and capitalist extraction. -

Climate factors influence the occurrence and development of grassland fire. An analysis of the climate conditions of fire occurrence can form the basis for a study of the temporal and spatial variability of grassland fire. The purpose of this paper is to study the effects of monthly time scale climate factors on the occurrence of grassland fire in HulunBuir, located in the northeast of the Inner Mongolia Autonomous Region in China. Based on the logistic regression method, we used the moderate-resolution imaging spectroradiometer (MODIS) active fire data products named thermal anomalies/fire daily L3 Global 1km (MOD14A1 (Terra) and MYD14A1 (Aqua)) and associated climate data for HulunBuir from 2000 to 2010, and established the model of grassland fire climate index. The results showed that monthly maximum temperature, monthly sunshine hours and monthly average wind speed were all positively correlated with the fire climate index; monthly precipitation, monthly average temperature, monthly average relative humidity, monthly minimum relative humidity and the number of days with monthly precipitation greater than or equal to 5 mm were all negatively correlated with the fire climate index. -

Firstly, the situation and challenges of China’s power green development is analyzed. On this basis, the power green development models are categorized into two typical research objects, which are multi-energy synergy mode, represented by integrated energy systems, and multi-energy combination mode with clean energy participation. The key points of the green power development model with the consumption of new energy as the core are reviewed, and then China’s exploration of the power green development system and the latest research results are reviewed. -

One of the main factors contributing to wind power forecast inaccuracies is the occurrence of large changes in wind power output over a short amount of time, also called “ramp events”. In this paper, we assess the behaviour and causality of 1183 ramp events at a large wind farm site located in Victoria (southeast Australia). We address the relative importance of primary engineering and meteorological processes inducing ramps through an automatic ramp categorisation scheme. Ramp features such as ramp amplitude, shape, diurnal cycle and seasonality are further discussed, and several case studies are presented. It is shown that ramps at the study site are mostly associated with frontal activity (46 %) and that wind power fluctuations tend to plateau before and after the ramps. The research further demonstrates the wide range of temporal scales and behaviours inherent to intra-hourly wind power ramps at the wind farm scale. 1 Introduction hourly) ramp forecasts (Zhang et al., 2017; Cui et al., 2015; Gallego et al., 2015a). -
