The purpose of this study is to learn the characteristics of the local residential forms and their usage, reveal the relationship between these characteristics and villagers’ lifestyles, and grasp the villagers’ evaluation of the satisfaction on living space, by the investigation of 168 questionnaires, 16 families in-depth interviews and survey mapping in the W, Y and Z villages of Suopo Township, Danba County, Sichuan Province. The resulted showed that: 1) Residents have obvious uniform features, mostly 3 - 5 layers of single-family residences, mostly in the area of 400 - 500 m2. The height of the house and the rooms has a relatively fixed modulus. 2) In the survey of the usage of local dwelling houses, it was found that farmers have a fixed model for the use of residential buildings. Most of the living activities are gathered in their own courtyards, and the utilization of the living room is usually limited. The floors above the second floor often have the terrace formed by the retreat to dry the food. There are often more bedrooms for spare, more than 90% of the family of four or more have two or more living rooms. 3) The residential area is embodied in both horizontal and vertical directions: the first floor of the indoor room from the courtyard to the dining room has the property of semi-open and semi-private space, and it is the main place for neighborhood interaction;and the rooms of the second and above are more private. 4) In the long process of life, the form and usage of houses will change with the changes of external factors. The traditional dwelling houses will be built or renovated, accounting for about 36% of the total amount surveyed.展开更多

According to the research, debris flow in Qiongshan Ravine is arosed by the fluidization of landslide. It had been rained about 70 days before debris flow occurred. That made the sediments in the gully to near to saturated or saturated in water. Being affect by the steep geography, the sediments occurrence peristalsis to transform, parts of soil bodies start disintegrate. All the sediments become transforming with water inleakaging to sediments, and than foreside slope flow to gully quickly after becoming fluidization. And the sediments come into being the debris flow with the water of the gully joining.展开更多

The former included chlorite, biotite, garnet, staurolite, kyanite and sillimanite zones, while the latter only developed silimanite+muscovite and sillimanite+K-feldspar zones. Integrated study has been carried on metamorphic reactions of garnet production and consumption, P-T paths and P-T-X-M phase relation and thermal tectonic model for Danba metamorphic zones. Petrological textures in thin sections show that garnet production and consumption in kyanite-sillimanite zone is mainly attributed to Chl+Ms+Pl+Q= Grt+Bt+H2O and kyanite=sillimanite respectively. Based on mineral compositions, the geothermobarometry gives an average P, T condition of (4.9±0.3)×108 Pa, 543±30 ℃ for the first growth stage of the garnet and (5.8±0.3)×108 Pa, 534±29 ℃ for the second stage of garnet growth respectively. Anti-counter clockwise P-T paths were drawn using Gibbs method by NCMnKFMASH system for sample G98686 in the kyanite zone. The P-T-X-M modeling for the first mineral assemblages shows that the prediction is similar to the measured values in gossular, almandine and spessartine but mole fraction of pyrope and Fe/(Fe+Mg) deviated far from the contours; while that for the second mineral assemblages exhibits that the prediction is consistent with the measured value of pyrope, grossular content and Fe/(Fe+Mg) of garnet. A thermal tectonic model that there are at least three structure levels across the thrust-decollement zones is presented according to the P-T paths, metamorphic grades and deformation styles for the staurolite-kyanite zone of the Barrovian type metamorphism, which will provide some constraints for the evolution of the nappe complex.展开更多
