Fault slip and modern tectonic stress field in and around Kunming basin

Kunming basin is a Cenozoic faulted basin under the control of mainly SN-trending active faults. In and around the basin, there are a total of eight major active faults. Seismo-geological survey and fault slip observation show that the SN- and NE-trending active faults are mostly sinistral strike-slip faults, while the NW-trending faults are mostly dextral strike-slip faults. Using stress tensor inversion method with 706 active fault striation data at 22 measurement sites, we determined tectonic stress field of the study area. The result shows that modern tectonic stress field in and around Kunming basin is characterized by NNW-SSE compression, ENE-WSW extension, and strike-slip stress regimes. The maximum principal compressional stress (σ1) is oriented 335o^2o, with an average dip angle of 21°; the minimum (σ3) is oriented 44o^93o, with an average dip angle of 14°, and the intermediate (σ2) has a high, or nearly vertical, dip angle. The inversion result from fault slip data is consistent with the result from focal mechanism solutions.

Prevention of debris flow disasters on Chengdu-Kunming Railway

Chengdu\|Kunming Railway is an important transport line on southwestern China. However, this railway’s safety is often threatened by debris flows. How to effectively forecast and alarm the debris flow disasters and reduce the losses is the aim to study the prevention system in this paper. The factors to cause or influence debris flow are divided into four parts——the basin environmental factors, the basin meteoric factors, the prevention work’s elements and the flood\|relief work’s elements, and the prevention system is made up of three models——a judgment model to assess the debris flow gully’s seriousness, a forecast model to predict the debris flow’s occurrence and an alarm model to evaluate the debris flow’s disaster. Afterwards, a concise structure chart is worked out and verified by the field data from Chengdu\|Kunming Railway. This prevention system will provide beneficial reference for the debris flow’s monitoring network to be executed on Chengdu\|Kunming Railway.

Kunming mouse strain is less susceptible to elastase-induced abdominal aortic aneurysms

Background:Porcine pancreatic elastase(PPE)is successfully used to induce abdominal aortic aneurysm(AAA)in mice.However,differences between mouse strains in susceptibility to PPE induction have been reported.Kunming mouse is one of the most frequently used strains in China but whether it is suitable for induction of AAA by PPE application remains unclear.Methods:PPE infusion(1.5 units/ml)in temporary controlled aorta was performed to induce AAAs in both C57BL/6J and Kunming mice.Phosphatebuffered saline(PBS)application was used as vehicle control.The aorta diameters of all mice were measured at days 0 and 14 after surgery to evaluate the AAA formation.Results:After 14 days of PPE or PBS infusion,all mice were sacrificed and aorta tissues were collected for histological staining analysis.At the 14th day after infusion,PPE successfully induced aortic dilation in Kunming mice and typical AAA in C57BL/6J mice.The aorta diameter increased by 0.23 mm in Kunming mice after PPE infusion,while it was 0.72 mm in the C57BL/6J strain.PPE induced mild elastin degradation,smooth muscle cell(SMC)depletion and mural leucocyte infiltration in Kunming mice,but in PPE-sensitive C57BL/6J mice,it induced total loss of SMCs,elastin disappearance and diffused infiltrated leucocytes in aortic aneurysmal segments.The effects of PPE in inducing angiogenesis and upregulating matrix metalloproteinase 2 and 9 expression in Kunming mice were also weaker than that in C57BL/6J mice.Conclusion:At the reported dose of PPE,Kunming mouse is not as susceptible to AAA formation as C57BL/6J mice.The failure of PPE to induce AAA formation in Kunming mice may be associated to its inability to boost a strong inflammatory response.

Stochastic Food Deprivation Increases Cellular Immunity in Kunming Mice

Animals’ immunity is an important factor to determine their survival and fitness. Unpredictable food shortage is common to small mammals due to fluctuation of food resources throughout a year. In general, acute food deprivation (FD) inhibited immune function in rodents. In the present study we tested the hypothesis that stochastic FD would also suppress T cell-mediated immunity in mice. Fifteen adult male Kunming mice were randomly assigned into the Fed (n = 7) and FD (n = 8) groups, in which the latter were subjected to stochastic FD regime. Unexpectedly, T cell-mediated immunity assessed by PHA response was increased in the FD mice compared with the fed controls. However, body fat mass, wet thymus and spleen mass, white blood cells, serum leptin and corticosterone concentrations did not differ between the Fed and FD groups. Taken together, stochastic food deprivation can enhance cellular immunity in Kunming mice.

Application of Rhododendron Species (Ericaceae) in Green System of Kunming City in Yunnan, China

Species, application frequencies, habitat features and combination modes of Rhododendron species in Kunming City were studied through random sampling in different subareas of Kunming City. The results show that Rhododendron species were widely applied in parks, residential areas and street-side green spaces. Diversified application patterns presented excellent landscape effects, but only a few species were used, for example, Rhododendron pulchrum Sweet., R. hybridum, R. simsii var. simsii, while R. delavayi Franch. and R. simsii var. mesembrinum Rehd. were occasionally found. Landscaping features of Kunming were characterized by domination of Rhododendron species, advantages and problems of Rhododendron species in landscaping of Kunming City were analyzed. It was proposed that introduction and domestication of wild Rhododendron species should be enhanced, rich germplasm resources of Rhododendron species should be fully used, and more indigenous Rhododendron species applied.

Education Demand of New Generation Minority Migrant Workers in Kunming City and Survey of its Influence Factors

Based on the questionnaire survey for 431 new generation minority migrant workers in Kunming City,we carried out empirical research on education demands of these migrant workers and its influence factors.Survey results show that their education demands have significant features in learning purposes,contents,expenses,willingness,and manners,which are subject to subjective mentality,economic income,social relation network,as well as shortage in social supply of education and training.Therefore,apart from solving training problem of new generation minority migrant workers,government should also highly value their demands of training and arouse their enthusiasm for participation in training in accordance with cultural and psychological characteristics and living environment of these migrant workers.

Effect of Climate Changing in Kunming in Recent 65 Years and Technical Analysis of Sponge City Construction

By analyzing the climate records of Kunming from 1957 to 2016, Kunming’s average temperature has been found to be increasing in recent 65 years. The key problem lies in the temperature rise in recent 10 or more years by 0.4 ℃/10a and the annual range decrease at the same time, represented as the elevation of the lowest temperature and increasingly warmer winter in Kunming. With the warming climate, the precipitation has suffered a prominent fall, by 18.05 mm/a in the past 14 years. The relative humidity is in direct proportion to the precipitation, which explains less water and drier climate in Kunming. With “One increase and two decreases” of the three key climate indexes changes in Kunming in the past 65 years, this paper analyzed the necessity and general situation of the sponge city construction in the city, proposed the overall planning of sponge city construction at the macro level, selected the sponge technology based on the urban construction land types, and planned the regulation facilities based on the catchment area and green space structure. Moreover, the paper explored the sponge city planning at the meso level and the sponge city eco-engineering technology at the micro level.

Impairment of Di(2-Ethylhexyl) Phthalate on Cellular Immunity in Kunming Mice

Immunity is crucial to the health of animals and it can determine their survival and fitness. Di(2-ethylhexyl) phthalate (DEHP) is widely used as a plasticizer and hence is the most abundant phthalate in the environment. Exposure to DEHP is of great concern for human health. In the present study, we tested the hypothesis that exposure to DEHP would suppress T cell-mediated immunity in mice. Twenty adult male Kunming mice were randomly assigned into the control (n = 10) and the DEHP treatment (n = 10) groups. Both groups have free access to food and water, while the mice in the latter group drank DEHP solution (2000 mg/L) for 42 days. T cell-mediated immunity assessed by phytohaemagglutinin (PHA) response was depressed in the DEHP treated mice compared with the controls, however, wet thymus and spleen mass, white blood cells were not influenced by DEHP treatment. Taken together, different immunological parameters responded differently to DEHP treatment in Kunming mice.

Analysis on the Change Characteristics of the Correlation between Land Use Structure and Energy Consumption and Carbon Emissions in Kunming from 1997 to 2017

This study takes Kunming City, Yunnan Province, China as the research area, to provide reference basis for revealing the change law of land use structure and energy consumption and carbon emissions in Kunming, optimizing land use structure and realizing the development of low-carbon city. Based on the data of land use structure and energy consumption in Kunming from 1997 to 2017, based on the estimation of total energy consumption carbon emissions, carbon intensity and per capita carbon emissions, the correlation between land use structure and energy consumption carbon emissions in Kunming has been calculated and analyzed in the past 20 years. Results: 1) The total amount of carbon emissions in Kunming has increased significantly in the past 20 years. It increased from 34.46 × 105 t to 95.09 × 105 t, an increase of about 2.8 times. 2) The types of land use with the highest correlation between land use structure and total carbon emissions of energy consumption, carbon emission intensity and per capita carbon emissions are urban and village and industrial and mining land (0.8258), cultivated land (0.8733) and garden land (0.7971) respectively. 3) The correlation between construction land and total carbon emissions is greater than that of agricultural land. Conclusion: There is a close correlation between land use structure and carbon emissions from energy consumption in Kunming.
