This article evaluated the plantation potential of Pistacia chinensis in Sichuan Province of China based on the spatial analyst technology of Geographic Information System and Analytic Hierarchy Process. The evaluation results show that the high suitable, suitable, moderate suitable and no suitable areas for the plantation of P. chinensis are 28×104hm2, 160×104hm2, 177×104hm2 and 690×104hm2 respectively. The high suitable areas of shrub land, open forest land and unutilized land for its plantation are 9×104hm2, 16×104hm2 and 3×104hm2 respectively. The high suitable regions distribute in fifteen prefecture-level cities. Yibin City has the biggest high suitable area with 4.92×104hm2. Dazhou City has the biggest suitable area of 23.47×104hm2. Ganzi Tibetan Autonomous Prefecture and Aba Tibetan and Qiang Autonomous Prefecture aren’t suitable for its plantation basically. The evaluation results can provide scientific basis for the planting plan of P. chinensis to a certain extent.
Why table olive is still not popular with Chinese consumers after its introduction to China for more than 50 years? As scientific output can reflect the applications of their study objects, to showcase the situation of Chinese table olive studies and to find out the possible answers to this question, we performed statistical analyses based on the Science Citation Index Expanded (SCI-E) database and the China Academic Journals Full-text Database (CJFD). Results show that the R & D of China's table olive sector are mainly focused on the introduction and cultivation of olives trees (Olea europaea L.) as well as the extraction of their high-value pharmaceutical and organic components, but rarely involve specific processing issues. However, the Chinese papers mostly report the results of table olive processing as well as the industrialization and the products with Chinese characteristics though the studies on these types of products have not been carried out in a comprehensive and systematic way. Chinese table olive researchers should consolidate the exchange and study with the non-Mediterranean countries, whose scientific output on table olives are worth of reference, such as Denmark, the UK, and the US, while maintaining communications with the scientists in Mediterranean countries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
