Materials and Methods Study Area Different ecological characteristics of the aquatic environment should have different ecological criteria.
The taxa were identified to species or genus level (for determination keys, see Severin et al., 2003) and counted using a stereo microscope (Wild Heerbrugg M3Z, Heerbrugg, Switzerland, max. 40).

Introduction Agricultural circular economy follows the law of ecological economic system and social economic system with aim of sustainable development and principle of minimization, recycle and resource, which minimize input amounts of resources and materials, and reduce ecological destruction and environmental pollution in the process of agricultural production to harvest more and more, and better and better agricultural products and realize ideal combination of agricultural ecological system and human socioeconomic system.
Central first document of 2004 pointed out “ecological engineering of returning farmland to forests or grassland and wetland protection” and “comprehensive improvement of quality and safety of agricultural products".
Therefore, increasing input level of reduced resources, improving the ecological environment and attaining the sustained and stable development of agriculture are the keys to achieve the goals of the development of agricultural circular economy of China.

Analysis for Gas Control Technology of Coal Mine in Southwest Guizhou Li Qingsong1,2,a, Li Guohong1,2,b,Heng Xianwei1,2,cZhang Shujin1,2,d 1Guizhou Coal Mine Design and Research Institute, Guiyang, Guizhou 550025; 2Guizhou Province Engineering Technology Research Center for Coal Gas Prevention & Control, Guizhou Guiyang 550025 aliqingsong@126.com, b85653214@qq.com, c272160330@qq.com, d328833372@qq.com Keywords: Gas Occurrence; Gas Control; Coal Mining Area of Southwest Guizhou Abstract: Through on-site inspection for the typical coal mines of each coal tectonic units in Southwest Guizhou as well as analysis of gas parameter, highlight information and gas control technology, the thesis makes the following conclusions.
With regard to on-site reference materials involving mine gas, there are no original gas content and pressure data.

With the improvement of material life, the protection awareness of family property is growing, and the approaches of installing security doors, anti-theft network not only impede the aesthetic outlook, but also do not conform to fire safety requirements, and even cannot prevent the residential intrusion of criminals; In addition, if the family member encountered the emergency, such as illness and cannot dial calls in a timely manner, it would be very dangerous.
The hardware chip that this design uses is AT89S52 chip, and selects 8 green LED indicator lights, 8 LED digital display tubes, and 3 of which are then connect to the INT1, T0, T1 of single chip microcontroller respectively, so as to receive the keys of the external signal, in addition, it also uses a 74LS245 module and two 74ALS573 module.
Conclusion With the development of economy, as well as the increasing material and cultural demands of the people, smart home system can greatly improve the quality of life of the people, and bring highly intelligent life for people, and is bound to be the favor of people of all ages.

Because of the potential layers distribution longitudinal crisscross, the bed series and intervals of the key layers were difficult to determine, the corresponding tap the technology was difficult.
Compared and analyzed liquid producing profile materials of 35 producing wells before and after adjustment, after adjustment sandstone proportion and effective thickness using proportion increased to 78.9% and 87.2%, improved 6.3 percentage and 8.2 percentage respectively, when GI10~GIII spacing was down to 175, the thin-bad reservoir using significantly improved, the thin-bad layers and outer tables which permeability less than 0.5m using reached to 70%, increased by more than 10 percentage, with further reduce using difference between layers.
