With the continuous improvement of transportation facilities and information networks, the obstruction of distance in geographic space has gradually weakened, and the hotspots of urban geography research have gradually changed from the previous city hierarchy to the characteristics of urban connections and networks. As the main carrier and manifestation of elements, mobility such as people and material, traf ic flow is of great significance for understanding the characteristics of spatial connection. In this paper, Harbin-Changchun agglomeration proposed by China's New Urbanization Plan (2014-2020) is taken as a research object. With the data of intercity passenger traf ic flow including highway and railway passenger trips between 73 county-level spatial units in the research area, a traf ic flow model is constructed to measure the intensity of spatial connection. Using social network analysis method, the characteristics of spatial connection of Harbin-Changchun urban agglomeration are analyzed, and the results are visualized with ArcGIS technique. The results show that the spatial connection of the Harbin-Changchun urban agglomeration based on traf ic flow presents a distance attenuation ef ect that weakens in the directions of "Harbin-Daqing-Qiqihar-Mudanjiang" and "Changchun-Jilin-Tumen", and the connection strength of Harbin or Changchun districts and other spatial units is the strongest, follow by Daqing, Qiqihar or Jilin districts and other spatial units; the network is highly centralized, the core city has the dominant role on the whole network, and the connection between network nodes is not balanced; the connection nodes present a dual- core-edge hierarchical distribution; the network based on railway shift of Harbin-Changchun urban agglomeration can be divided into four subgroups,showing block distribution characteristic in Harbin-Changchun urban agglomeration. The research can provide support for the proposal of regionally coordinated sustainable development strategies of Harbin-Changchun urban agglomeration.

Grouper fish is a type of reef fish that is exported as a commodity to various countries such as Hong Kong, Japan, Singapore and China. Grouper fish can be cultivated using floating net cages and have a high selling price (high profit) but also have a high risk (high risk), thus affecting the market and the number of grouper aquaculture. The purpose of this research is to determine the socioeconomic impact of the use of floating net on grouper farmers. The determination of the research area was carried out deliberately in Situbondo Regency. The study was conducted with a qualitative approach. Data collection is done by observation and depth interview. The informants of the research were determined intentionally, namely grouper fish farmers who do aquaculture with floating net cages. The data analysis method uses Milles and Huberman. The results showed that the use of floating nets for grouper culture had social and economic impacts. The social impact on grouper farmers is the formation of grouper farmers, thus creating a social network in the form of interaction between farmers; construction of supporting facilities for the development of aquaculture businesses but also raises social prejudices between farmers because of frequent theft of fish in floating nets. While the economic impact is based on increasing grouper production which has a direct impact on the income of grouper farmers. Keywords : Floating net, grouper fish farmers, socio-economic impacts

In order to analyse the main influencing factors of civil aviation passenger transport volume in multi Airport area. Correlation analysis, stepwise linear regression analysis and Grainger causality test were used to analyse the influence factors of civil aviation passenger traffic volume, to eliminate the invalid factors, a regression model is established to analyse the causal relationship between the various factors and air passenger volume. Through the analysis of the Yangtze River Delta region, it is concluded that the number of inbound tourists, the railway mileage and the volume of railway passenger transport are the main factors affecting the Yangtze River Delta region. Through the Grainger causality test, the air passenger volume of the Yangtze River Delta has one-way influence on the railway passenger traffic volume.

Entropy, founded in 1999, is an emerging international journal in the field of entropy and information studies. In the year of 2018, the journal enjoyed its 20th anniversary, and therefore, it is quite reasonable and meaningful to conduct a retrospective as its birthday gift. In accordance with Entropy’s distinctive name and research area, this paper creatively provides a bibliometric analysis method to not only look back at the vicissitude of the entire entropy topic, but also witness the journal’s growth and influence during this process. Based on 123,063 records extracted from the Web of Science, the work in sequence analyzes publication outputs, high-cited literature, and reference co-citation networks, in the aspects of the topic and the journal, respectively. The results indicate that the topic now has become a tremendous research domain and is still roaring ahead with great potentiality, widely researched by different kinds of disciplines. The most significant hotspots so far are suggested as the theoretical or practical innovation of graph entropy, permutation entropy, and pseudo-additive entropy. Furthermore, with the rapid growth in recent years, Entropy has attracted many dominant authors of the topic and experiences a distinctive geographical publication distribution. More importantly, in the midst of the topic, the journal has made enormous contributions to major research areas, particularly being a spear head in the studies of multiscale entropy and permutation entropy.

This paper takes Yingtai area which is located in the south of Qijia-Gulong sag and part of central sag area in the north of the Songliao Basin as the research area. Then combining all information of core, logging, three-dimensional seism and well testing data, it studies the reservoir type and oil-water distribution characteristics of Heidimiao by analyzing the comparison charts of sandstone, profile map of reservoir, T07 structure diagram, well testing data, stratum thickness, sandstone thickness, ratio of sandstone thickness to stratum thickness, porosity values, permeability contour maps. The reservoir lithology of Heidimiao oil layer is siltstone-oriented with poor physical property. The main controlling factor of oil-water distribution is the lithology, followed by the structure. Heidimiao oil layer mainly includes three types, lithological oil reservoir, lithological - structural oil reservoir and structural oil reservoir, among which lithological reservoir plays a dominant role. Its oil-water distribution is characterized by the pattern of upper-water and bottom-oil; when the fault acts as the pathway for the longitudinal migration of oil and gas, the pattern changes to the upper-oil and bottom-water. This research could provide reliable geological basis for the research of old well re-examination, favorable area evaluation and horizontal well drilling design.
