As the common method of reference material, regional eco-agricultural tourism income approximately reflects the level of eco-agricultural tourism development in the region in the sample period.
Conclusions There is a lot of research material for the regional eco-agricultural tourism in China, but none is by the method of time series.

The feed material selected for study is sweet lime peel.
Experimental 2.1 Raw material.
Waste sweet lime peels were collected after juice extraction as the raw material for production of sweet lime essential oil.
The yield of essential oil was calculated for each run by using the equation [10, 11] Yield of essential oil (%) = (amount of essential oil (g) obtained)/ (amount of raw materials (g) used) x100 The essential oil samples were analyzed for their purity by using Gas Chromatography Mass Spectrometry (GC-MS) [12].

Study on Corrosion Resistance of Several Fe-based Amorphous Alloys Xiujuan Tian 1, a, Wanfu Liu 1, b and Kun Xie 1, c 1College of Materials Science and Engineering, Shandong University of Science and Technology, Qingdao, Shandong 266590 atxj79@sohu.com, b1048525437@163.com, cxie.kun@126.com Keywords: Fe-based amorphous, Corrosion behavior, Crystalline temperature, NaCl solution.
The amorphous forming ability and crystallization temperature of materials were characterized by differential scanning calorimetry (DSC).
New bulk metallic glass with excellent corrosion resistance, is hopefully used as structure steel materials in ship and nuclear water tank [5, 6].

A combination of both morphologies renders a tough and resilient material as it is.
One of the most important parameters for amorphous or semi-crystalline materials is their glass transition temperature Tg As the temperature increases and crosses Tg, the material behavior changes from glassy to rubbery or liquid-like.

Wheat-straw from north China and straw or water bamboo leaves from south China are all feasible as raw materials of BCP-mat, and the Fig.1 is the structure of BCP-Mat which is made of straw.
The seed bags are made of water-soluble materials that can be dissolved or fractured under water for a while and settled by straws and straw ropes (Fig.2), and the seeds can easily fall into the bed after bag dissolution.
Secondly, raw materials are agriculture wastes which are cheap, abundant and eco-friendly.
