As a result of different densities of industrial energy consumption, the industrial structure becomes a key factor of CO2 emissions.
A typical high-carbon industry includes coal power, building materials (cement, glass, etc.), chemicals (gasoline, caustic soda, etc.), automotive, and real estate [4].
The government should increase investment, construct tree shelter, the green channel, suburban living forest and other ecological engineering.

Keywords: Landscape and famous scenery, Landscape tourism planning, Regional culture
Abstract: Landscape tourism planning is an important special planning of landscape and famous scenery planning.
In a bread sense, the regional culture is created by regional people through the physical and mental in long-term historical development process and the result is accumulated and developed widely and constantly, which is all of results and achievements of material and spirit.
Therefore, how to highlight the theme of landscape and famous scenery and determine the scenic positioning and properties are the planning keys and difficulties through excavating and displaying regional natural environment characteristics and historical cultural connotation, which has the great significance for the future development of China’s landscape and famous scenery.
There are a lot of bamboos piled up, while displays its material function using the bamboo resources, through planning can excavate culture transmission function and increase bamboo knowledge and awareness, also affiliate the human and bamboo to harmonious development.

Keywords: P2O5/CaCl2/Fe3O4 composite catalysts, oleic methyl ester, biodiesel.
A pretreatment esterification step must be considered as mandatory for oils with high content of FFA, such as in waste oils, to eliminate the free acidity, which should be reduced to levels below 1% w/w.[8] One alternative process to produce biodiesel is the esterification of free fatty acid in the presence of a acid used as catalyst. [9] Thus, the improvement of the esterification step could represent one of the key points that need to be studied.
Dissolved about 125mg FAME products and 2.5mL inner standard material, heptadecanonic methyl ester, to the 2.5mL acetic ether in a reagent bottle, and injected 1 ml into GC injection system after thorough mixed.
By adding 1% catalyst (w/w) against material fatty acid, 50%, 60% and 80% conversions of oleic acid were found by Fe3O4 , CaCl2 and P2O5 respectively.

Abstract.
It can also improve the conditions of sheet metal processing, make better use of the material formability than conventional forming technology, raise the sheet metal formability, get more complicated parts [1], achieve to flexible digital manufacturing of sheet metal.
Research status One of the earliest researchers of high-pressure WJISMF is Hideo ISEKI, who worked in department of Mechanical Engineering, Tokyo Institute of technology.
With the forming semi-cone angle reduces, the thickness of sheet metal deformation zone will become thin, when the thickness decreases to a certain extent, material will fracture due to instability.

Keywords: Polychromatic set, PCB assembly optimization, Computable model.
Computable model based on Polychromatic Set The key of PCB assembly optimization with multiple tasks and machines is able to formulate an integrated model which can describe complex constraint relationships and dynamic characteristics.
The changes of internal production environment refer to the change of PCB assembly system caused by disturbance of unpredicted event (e.g. machine failure, material shortage).
