The results showed that the traditional villages in Guangdong were distributed compactly, which was similar to that in other provinces; on the prefecture-level city scale, they were mainly distributed in Meizhou, Qingyuan, Zhanjiang, and Zhaoqing, showing a central distribution; on the regional scale, they were mainly distributed in northern Guangdong and the Pearl River Delta, indicating an unbalanced distribution; their density of spatial distribution showed a significant difference with a provincial distribution density of 0.59 per thousand km^2 and the highest distribution density of 2.14 per thousand km^2; there were four gathering areas accommodating many traditional villages, namely Meizhou-Chaoshan area, Guangfo-Dongguan area, Leizhou in Zhanjiang, and Lianzhou in Qingyuan; the spatial distribution of traditional villages, which presented a pattern of hot spot—sub-hot spot—sub-cold spot—cold spot, had a significant global spatial autocorrelation, and areas in similar sizes were tending towards gathering; traditional villages in Guangdong belonged to the Cantonese-speaking group and Hakka-speaking group with a density of 0.59 per thousand km^2 and 0.48 per thousand km^2 respectively, and Han subgroup with the highest distribution density was the minority areas of 1.31 per thousand km^2, followed by Shaozhou dialect area with a density of 1.00 per thousand km^2.展开更多

In order to effectively enhance the beauty of the city's human landscape, authors of this paper, based on the public art dimension of metro, explore the artistic expression, problems, and countermeasures related to the enhancement of the beauty of human landscape, and solutions to the common failing of metropolises in the evolution of urban civilization, so as to optimize and spread the urban culture. It is hoped that this paper can cover the shortage of relevant domestic and international studies and provide a theoretical reference for the majority of man-made landscape researchers.展开更多

The results showed that Xinyang was rich in wild potted plants, with 74 families, 137 genera, and 379 species. Among them, angiosperms were the most common group, with 46 families, 92 genera, and 232 species. Bryophytes and ferns were also common in Xinyang, with 9 families, 22 genera, and 80 species as well as 13 families, 16 genera, and 58 species respectively. According to the purpose, wild potted plant resources can be grouped into three types: tree potted plants, landscape potted plants, and moss potted plants; according to the ornamental part, wild potted plant resources can be classified into five types: foliage plants, flowering plants, fruit-effect plants, synthetic plants, and special plants. Building up the ranks of penjing creators, giving full play to its advantages based on local resources, and producing penjing with local flavor, is the direction for future development of Xinyang penjing.展开更多

We extract the basic information of land use in areas around Sichuan Gymnasium Station in 2005, 2011, and 2016 through Google Earth in order to draw the map of land use status in three time nodes. We then analyze the degree of mixing and equilibrium, intensity of development of land, and land use patterns of areas around Sichuan Gymnasium Station with indexes including the area proportion of land use patterns, information entropy, and degree of equilibrium within a 1,000-m radius centered on the station, so as to reveal the spatial distribution characteristics of land around the station in different time nodes. Through comparative analysis, it is found that the development of rail transit has not significantly contributed to the boom of commerce and the development of the old city of Chengdu. We also analyze land use changes in areas around Sichuan Gymnasium Station in terms of space, and find that land use patterns in areas around commuter stations seem to be more complicated than that of the average station, and land use patterns in areas around Huaxiba Station and Nijiaqiao Station on Line 1, which opened first, are more complicated than that of Moziqiao Station and Yiguanmiao Station on Line 3. The original land use patterns formed in the old city often determine the selection of rail transit routes and rail transit stations. Adaptive stations do not play a decisive role in land use patterns in their surrounding areas, but have some impact on the plot ratio and building height of land for commercial use within the core area of the stations.展开更多

The improved entropy method was used to determine the weight, the Technique for Order of Preference by Similarity to Ideal Solution(TDPSIS) was used to calculate the capacity for sustainable development of the cities and counties and sort these cities and counties, and Arcgis10.2 was used to draw the provincewide distribution of the four guidelines. Thereupon, the author reached following conclusions: there was no big regional difference in the sustainable development capacity of cities and counties in Hainan, and they were basically in a general state of intermediate stage in the past four years; Haikou City and Sanya City, as the key cities, had a higher ability of sustainable development and had shown a remarkable capacity to drive the sustainable development of surrounding areas; according to the development level, the four guidelines were in the following order: resource utilization and environmental protection capacity, population development capacity, social support capacity, and economic development capacity.展开更多

The results showed that:(1) with a mean value of 135.36 g/m^2, grassland aboveground biomass showed a unimodal distribution from rise to decline as altitude increased, and reached its maximum of 176.79 ± 28.37 g/m^2 at an altitude of 2,900 m; with a mean value of 946.13 g/m^2, grassland underground biomass showed an uptrend as altitude increased, and reached its maximum of 1,301.19 ± 68.24 g/m^2 at an altitude of 3,000 m;(2) the difference between aboveground biomass and underground biomass in the grassland at different altitudes was significant;(3) values of root shoot ratio of the arid mountain grassland varied between 4.14–11.95;(4) values of soil moisture content of the arid mountain grassland varied between 9.23%–31.31%;(5) there was a positive correlation between aboveground biomass and underground biomass and the mean soil moisture content(p < 0.05), with a correlation coefficient of 0.778 4 and 0.784 3 respectively, soil layers with different moisture content made different contributions to grassland biomass, and moisture content in the soil layer where over-60-cm root systems were located was of significance to grassland biomass.展开更多
