响应面法在化工生产工艺优化中的应用

化工生产工艺的优化是提高产品产率、实现规模化生产的重要工作。响应面法是一种新兴的优化技术,是综合试验设计和数学建模的优化方法,可有效减少试验次数,考察各因素间的交互作用,通过模型优化求解,给出更准确的优化方案。在化工生产工艺优化中,响应面法是一个有效的优化技术。

Analysis of Land Use Change in Western Yunnan Plateau——Taking Midu County as an example

The research of land use/land cover change （LUCC） is the core content of global environmental change research and an important part of the sustainable development research. Taking the Midu County of western Yunnan Plateau as the example, GIS technology was used to make the spatial overlay with the land use database in 2009 and land change survey database in 2014 of Midu County, so as to analyze the changes of land use of the county, and reveal the law of land use change, with the aim to provide the basis for further rational utilization of land resources.

区域一体化背景下的城市群治理研究

城市群是我国城镇化建设的重要部分,城市群治理的目标是实现发展整合,更加注重城市之间的共享与合作。在区域一体化发展的背景下,城市群治理取得了显著效果,城市之间合作成为发展的必然趋势。基于此,本文对区域一体化背景下的城市群治理问题进行了研究。
