Taking Xingwen World Geopark as an example, through the research on tourist traffic carbon footprint, investigating the condition of carbon emissions of the tourist traffic, it is helpful to confirm the target of energy-wasting and emission reduction, provide reference for market positioning and management measures of low-carbon tourism development.
According to the horizontal comparison based on the data in 2013, the emission of CO2 from bus and car is 3387.391t and 6641.944t, account for 34% and 66%, respectively.

Introduction When satellite remote sensing image has the influence of cloud shadow, the reflection of corresponding objects will decrease due to the solar radiation’s reduction in the shadow region.
This method is also applicable for other image data.

The decrease of TEA content caused the reduction of the absorption bands intensity in the region of 1650cm −1 that corresponded to the stretching vibrations of the Aromatic ring in TEA.
Based on the spectral data obtained, it can be concluded that TEA and M-Pluronic F-127 are connected by intermolecular hydrogen bonds. 3.2 Micromorphology of composite membranes Fig. 2.

The simulation results of each model were transferred to the next one by data mapping method.
This is related to the reduction of the cross section area.

An increased fundamental understanding of the physical processes responsible for cleaning can lead to a narrowed distribution of physical forces and, as a result, to a reduction of damaged structures during the physical cleaning process.
The calculated transmission data have been verified with a hydrophone for the 1.67 MHz transducer.

Introduction With the development of industrial technologies, especially in automotive and aerospace industries, requirements on weight savings, reduction of fuel consumption and atmospheric pollution have attracted great attentions for lightweight structures.
The influences of various parameters on formation of weld bead, hardness, mechanical properties and microstructure were evaluated, which provided valuable data for later applications.

These kinds of tendencies, however, such as the elevation of aggregation and a reduction of oxygen delivery to tissues, are still in controversial [4].
The thickness of the cell-free layer was calculated by averaging the gray-scale data of raw images which were obtained by a high-speed CCD camera.

The surface areas were calculated with the Brunauer-Emmett-Teller (BET) method, using the adsorption data within the relative pressure (p/p0) range from 0.05 to 0.26.
In the meantime, the capillary condensation steps become less visible, accompanied by significant reductions of the hysteresis loops, indicating contraction or partly collapse of the mesopores.

Therefore, the precise classification of fine powder, which meets the requirement of the following process, becomes one of the vital technics in powder technology. [2] Several problems exit in the mechanical sieving classification of metal-powder as follows: (1) the screen blinding is serious when fine powder is processed which caused reduction of the throughput and sieving efficiency and a great loss of fine powder, (2) the screen is easily distorted and damaged when it is cleaned by means of high-frequency electromagnetic or ultrasonic vibration, (3) frequently replacement of the screen causing high labor intensity and low working efficiency and hetero-metal and non-metal materials could pollute the powder during the process of fixation and hermetization of screen , and (4) discretionarily adjustable separation size is unavailable because of the limitation of the sequence of mesh. [3] The problems mentioned above can be avoided by using other classification techniques without screen
In order to ensure the classification precision in practical processing, some methods can be used: 1) we could built up a system: the air flow velocity could be detected by a sensitive sensor, collection and transformation of the data are conducted by corresponding system, then the date will be putted into the computer, finally the computer send the commands to regulating system to precisely control the air flow velocity. 2) Appropriately broaden the separating room to reduce the fringe effect, and 3) choose the appropriate material for separating room in order to avoid the electrostatic effect between particles and material.

A large number of experimental data indicate that the formula is available[5], and the processing mode of multilayer circle heat conduction can be utilized.
