Abstract: We evaluated land suitability for Jatropha cultivation at a global scale under current and future climate scenarios. Areas that are suitable for Jatropha cultivation include southern South America, the west and southeast coasts of Africa, the north of South Asia, and the north and south coasts of Australia. In the predicted climate change scenarios, areas near the equator become less suitable for Jatropha cultivation, and areas further from the equator become more suitable. Our analyses suggest that the rank order of the six climate change scenarios, from the smallest to the largest effects on Jatropha cultivation, was as follows: B1, A1T/B2, A1B, A2, and A1FI.

Abstract: The article reviews the application of GIS technology to urban planning and the research progress on construction suitability evaluation. It points out that the present evaluation method invisibly weakens high eco-sensitivity areas and unsafe areas, and therefore the evaluation process can not objectively reflect the different angles of urban land use and its contradiction and unity. Thus, the article suggests strengthening the idea of giving priority to ecology and city safety through analyzing key sensitive factors and perfecting multi-factor superposition method. It explores a new idea for land suitability evaluation from three angles, that is, eco-sensitivity evaluation, construction suitability evaluation and city safety. An empirical study is conducted on the master planning of Hongya County Town.
