城市最初起源于地理景观的选择,地理格局对于城市景观起源和发展变化始终有着重要而深刻的意义.古都保护规划需要研究地理格局之中的城市景观时空变化和演替轨迹：春秋战国时期南京就有依山势修筑的军事堡垒,三国时期,东吴孙权依靠长江天堑在南京创建都城,依靠山川地形构建军事防御城墙,随后陆续有10个王朝建都南京,山脉水系始终是影响南京城市空间的重要因素;早先帝王依据自然唯物思想选址构筑城市,后来逐渐以唯心说法“王气”“风水”“紫光”等笼罩地理山川.探究地理视角的“南京古都风貌保护规划”新思路,依顺自然地理山水脉络探察城市起源遗址以及发展变迁古迹,分析现代建设破坏的主要地理地段,保护古都赖以生存的自然山脉河流脉络系统,为城市永续发展奠定基础.

Multifunctional agriculture has been growing concern in recent years, which represents the direction of the development of agriculture.. Henan Province is a major agricultural province in China, which has great sig- nificance for country＇ s food security. Scientific understanding of the evolution of Henan agriculture has great signif- icance for the correct formulation of agricultural development strategies and policies from the perspective of multi- functional agriculture. Since the founding of China, Henan agriculture has made brilliant achievements, but there are profound lessons. Henan＇ s grain output continued to increase from economic function, which made significant contribution to national food security, but the function of agricultural income has been greatly weakened;From so- cial function, the function of employment and social security for Henan agriculture still has special meaning; Form ecological function of agriculture, since beginning of the reform, its negative effects far outweigh the positive effect, the serious consequences has emerging. Function of cultural heritage has declined in market economy, but the leis- ure and tourism functions have sprung up everywhere.
