Chapter 5 Sinicization and Indigenization: the Emergence of the Yunnanese
Between Winds and Clouds Bin Yang Chapter 5 Sinicization and Indigenization: The Emergence of the Yunnanese Introduction As the state began sending soldiers and their families, predominantly Han Chinese, to Yunnan, 1 the Ming military presence there became part of a project of colonization. Soldiers were joined by land-hungry farmers, exiled officials, and profit-driven merchants so that, by the end of the Ming period, the Han Chinese had become the largest ethnic population in Yunnan. Dramatically changing local demography, and consequently economic and cultural patterns, this massive and diverse influx laid the foundations for the social makeup of contemporary Yunnan. The interaction of the large numbers of Han immigrants with the indigenous peoples created a 2 new hybrid society, some members of which began to identify themselves as Yunnanese (yunnanren) for the first time. Previously, there had been no such concept of unity, since the indigenous peoples differentiated themselves by ethnicity or clan and tribal affiliations. This chapter will explore the process that led to this new identity and its reciprocal impact on the concept of Chineseness. Using primary sources, I will first introduce the indigenous peoples and their social customs 3 during the Yuan and early Ming period before the massive influx of Chinese immigrants. Second, I will review the migration waves during the Ming Dynasty and examine interactions between Han Chinese and the indigenous population. The giant and far-reaching impact of Han migrations on local society, or the process of sinicization, that has drawn a lot of scholarly attention, will be further examined here; the influence of the indigenous culture on Chinese migrants—a process that has won little attention—will also be scrutinized. -
Ecological Risk Assessment of Typical Plateau Lakes
E3S Web of Conferences 267, 01028 (2021) https://doi.org/10.1051/e3sconf/202126701028 ICESCE 2021 Ecological Risk Assessment of Typical Plateau Lakes Yuyadong1.2*, Yankun2 1.School of Ecology and Environmental Science Yunnan University, China 2.The Ecological and Environmental Monitoring Station of DEEY in Kunming, China Abstract. Plateau lakes have significant ecological value. With economic development, lake pollution and ecological degradation have become increasingly prominent. There are many ecological risk assessment methods. This article combines four different ecological risk assessment methods including single-factor pollution index, geological accumulation index method, potential risk index method, and pollution load index method to analyze the heavy metal pollution in Yangzong seabed mud as comprehensively as possible. It shows that the results obtained by different ecological risk assessment methods are slightly different. The overall trends of the geological pollution index and the single-factor pollution index are similar. In terms of time, except for the two elements of mercury and cadmium, the contents of other heavy metals in 2019 are lower than in 2018, indicating that heavy metal pollution has decreased in 2019; from the perspective of spatial distribution, In 2018, the overall pollution level on the south side of Yangzonghai was higher than that in the central and northern regions of Yangzonghai . On the whole, whether it is the potential risk index or the appropriate pollution load index, the pollution level on the south side of Yangzonghai is higher than that in the central and northern areas of Yangzonghai, and the northern area has the least pollution. ecosystems is relatively reduced, which makes the economic development of plateau lake basins face severe 1 Introduction challenges. -

Water Resource Risk Assessment Based on Non-Point Source Pollution
water Article Water Resource Risk Assessment Based on Non-Point Source Pollution Xiaodie Yuan and Zhang Jun * School of Architecture and Planning, Yunnan University, Kunming 650500, China; [email protected] * Correspondence: [email protected] Abstract: As one of the most important causes of water quality deterioration, NPS (non-point source) pollution has become an urgent environmental and livelihood issue. To date, there have been only a few studies focusing on NPS pollution conforming to the estimation, and the pollution sources are mainly concentrated in nitrogen and phosphorus nutrients. Unlike studies that only consider the intensity of nitrogen and phosphorus loads, the NPS pollution risk for the China’s Fuxian Lake Basin was evaluated in this study by using IECM (Improve Export Coefficient Model) and RUSLE (Revised Universal Soil Loss Equation) models to estimate nitrogen and phosphorus loads and soil loss and by using a multi-factor NPS pollution risk assessment index established on the basis of the data mentioned above. First, the results showed that the load intensity of nitrogen and phosphorus pollution in the Fuxian Lake Basin is low, so agricultural production and life are important sources of pollution. Second, the soil loss degree of erosion in the Fuxian Lake is mild, so topography is one of the most important factors affecting soil erosion. Third, the risk of NPS pollution in the Fuxian Lake Basin is at a medium level and its spatial distribution characteristics are similar to the intensity characteristics of nitrogen and phosphorus loss. Nitrogen, phosphorus, sediment, and mean concentrations are important factors affecting NPS pollution. -
Grain Size and Pollen of Sediments in Wanghu Lake (Central China) Linked to Hydro-Environmental Changes

The implications of such measures, however, remain unclear, since watershed hydrology and the related transfer of materials to the lake are affected by local climate variables, hydrological shifts, and vegetation cover variables. Sediment from Wanghu Lake in the middle reaches of the Yangtze River have apparently been affected by land cover changes and lake-river system transitions caused by a sluice gate built at Fuchi in 1967. These changes influenced the watershed hydrology, thereby confounding paleoclimatic and paleohydrologic interpretations by proxy records in sediment cores. We collected sediment cores from the center of Wanghu Lake and analyzed trends in pollen and physical properties through sedimentary records to investigate land cover changes and hydrological transitions during the past 90 years. The grain size of the sediment core increased with precipitation and the significant relationships between pollen and grain size after 1967 indicated that sediment transfer to the lake was controlled by rainfall and land cover changes due to human-induced deforestation and farming in the lake catchment. -
