China has developed some satellite series such as meteorological satellite series Fengyun (FY), ocean satellite series Haiyang (HY), Earth resources satellite series Ziyuan (ZY), environment and disaster monitoring small satellite constellation (HJ), as well as Shijian satellite series (SJ) for new technological experiments, and has formed a complete Earth observation satellite and ground application...
Three-North Shelterbelt Program (TNSP) has been implemented in China since 1978 to increase forest coverage, control soil and water loss, and improve environment. Monitoring ecological management could provide the effect of the program and form the information base upon which sound planning decisions were made. The paper monitored forest resources and soil erosion on one example of Zhongyang County,...
There has been a tremendous rise in the growth of online social networks all over the world in recent years. This has resulted in a large amount of content created and propagated at an incessant rate, all competing with each other to attract enough attention and become trends. In this paper, we analyze the temporal aspect of trends and trend-setters in Sina Weibo, contrasting it with earlier observations...
With the sustaining economic development in China, the timely, accurate and objective agricultural production information service has been highly demanded by the central and provincial governments. China Agricultural Remote Sensing Monitoring System (CHARMS) is an operational agricultural monitoring system in the Ministry of Agriculture of China to meet this demand.
The monitoring about the changes of land use and cover and NPP in mining area is one of hot spots in the field of resources and environment. Combining with ground field survey data, the remote sensing image in different periods in mining area and the geographic information technology are used to study the changes of Land Use and Cover and NPP. The results show that the degree of the change of land...
Observations of tropospheric column densities of NO2 obtained from the satellite instruments OMI for the period of 2005 to 2010 are used to derive average monthly and seasonal variations over China. The obtained results indicate that NO2 has an imbalanced spatial distribution with the highest level in North China, Yangtze Rive Delta region and Pearl River Delta region. The seasonal pattern of the...
Ambient levels of formaldehyde and BTEX (benzene, toluene and xylene) compounds were monitored at seven residential areas in Xicheng District, Beijing, during the period of November-December 2009. Formaldehyde was collected using 2, 4 dinitmphenyihydmzine (DNPH) modified silica tube and analyzed by HPLC. BTEX compounds were collected with activated carbon tube and analyzed by GC-FID. The concentrations...
The development of Shenyang's real estate market is healthy, stable and sustainable in recent years and has contributed much to the development of Shenyang's economy. However, there is still lacking of index system that reflects the situation of Shenyang's real estate market. According to the feature of real estate price indexes in China and different cities and through the price analysis to housing...
In recent years, safety problem of bridges becomes a public topic, and threatens people's lives and property; it also has become an indispensable hidden danger. This paper analyzes the main problems existing in the safety management, provides some improving measures, and points out the importance of safety operation on construction sites and its later maintenance and management. In order to ensure...
This study using computer image processing and artificial neural network sensor technologies constructs a method of identifying ice slurry density based on the value of ice color image. The method is applied to the Jinan section of the Yellow River through the ice image acquisition, R/G color extraction, network learning and training, the final output target value of ice or water, and the actual image...
This paper study base on the engineering fact of Diaozhongba landslide. A new method of data processing based on time series analysis of wavelet technology was used to refined data processing function of wavelet. The grey system theory is attenuates the primitive sequence through the production transformation randomness. The Established GM (1,1) model with this landslide slope government process actual...
To monitor the land sandy desertification dynamic change accurately in Duolun, the desertification was classified and evaluated based on the land use point of view and the evaluation index system based on land use was set up. TM image was decomposed by linear spectral mixture mode and the vegetation component of TM image was amended by the high-resolution satellite image to extract the information...
As an important component of smart power grid, smart transmission line has played a decisive role in the construction of China's smart power grid. In the paper, the characteristics of smart transmission line are introduced, the main status parameters of transmission line are given, the key technologies of transmission line state monitoring are analyzed, and a power line on-line monitoring system based...
In this paper, stormwater runoff from an urban traffic road and building located in Beijing, China, was characterized to measure the stormwater runoff discharge rates and pollutant concentrations. Based on monitoring, the runoff water quality on two underlying surface conditions was analyzed. The temporal dynamics of chemical oxygen demand (COD), NH3-N, NO3-N and total phosphorus (TP) were similar...
Synthetic aperture radar interferometry (InSAR) is a novel space observation technique from satellite which enjoys the merits of high spatial resolution, high precision and area matrix surveying. Especially, the Differential InSAR (DInSAR) technique has been applied to detect and monitor ground deformation. In this study the displacement on line of sight has been acquired with two-pass DInSAR processing...
Organ phosphorus pesticides (OPs) were first synthesized in large quantities in the 1940's and are now widely used in China. Although OPs can degrade rapidly, they are also highly toxic. Indeed, many cases of poisoning in China, especially from vegetable sources, were attributed to the presence of OPs in large quantities. Even though the use of highly toxic pesticides in vegetables has been banned...
As technologies advance constantly, households respond to energy efficiency improvement with higher energy consumption per unit. The current rapid economic development and the other latent reason - rebound effect induce such phenomenon. Rebound effect has long been ignored in the household energy efficiency of China while it has been recognized widely all over the world. Since there exists a high...
Bosten Lake, which locates in arid and desert zone, is the largest lake in Xinjiang, and is the largest inland freshwater lake in China. It has giant value in environment, ecology and economy. The water level of Bosten Lake has taken place tremendously in the recent 50 years, the water level descended from 1048m above sea level in 1958 to that of 1045m in 1987, and ascended from 1045m to 1048.9m during...
Sampling method was employed to investigate the structure and ecological benefits of street trees in the area within Second Ring Road of Shenyang. The study area covers about 161 km2, and 61 main roads. Based on the field data, the i-Tree (STRATUM) model was run to analyze street trees' structure and ecological benefits. The results showed that there were 19 street tree species in the study area,...
The paper presents the principle and calculation process of the principal component analysis which is a useful method of water quality assessment. Eight indicators include dissolved oxygen, permanganate index, BOD, ammonia nitrogen, copper, zinc, volatile phenol, oil in 20 monitoring sections of Ningbo urban river were analyzed by using principal component analysis. Three factors with 86.67% of accumulated...
