高速城镇化背景下山地城镇空间拓展问题的分析——以云南临沧为例

在高速城镇化背景下，临沧市的山地城镇在空间扩展中遇到了诸如城镇周边耕地被大量侵蚀、新城空置、城镇地质灾害隐患加大、城镇外围生态景观破坏，城镇地域特色丧失等一系列问题。这些问题主要是由于以下几个方面的原因造成的：（1）城镇建设中总是优先选择建设成本低廉的农田导致对耕地的侵蚀；（2）落后的工业化进程制约城镇化的持续发展导致新城空置、经济活力不足；（3）城镇空间采用蔓延式的拓展模式导致城镇地质灾害隐患加大和城镇外围生态景观破坏；（4）缺乏对城市特色的提炼导致山地城镇地域特色丧失。

ANALYSIS ON DIFFICULTIES OF MOUNTAINOUS TOWNS'SPATIAL EXPANSION IN THE PROCESS OF THE RAPID URBANIZATION——A CASE STUDY OF LINCANG OF YUNNAN PROVINCE

The mountainous towns of Lincang have to face many difficulties in their process of spatial expansion with the rapidly urbanization, such as reduction of cultivated land around the towns, lower using rate of new towns, hidden danger of the geological disaster, destruction of the towns landscape and losing of the towns＇ character. All of these are caused by following four reasons： （ 1 ） Prioritizing selection of cultivated land, which cost less, is the main cause of reduction of cultivated land around the towns. （2） The backward industrialization, which restricts towns＇ urbanization, is the main cause of lower using rate of new towns and economy recession of new towns. （3） The towns sprawl extension style is the main cause of the hidden danger of the geological disaster and the destruction of the towns＇ landscape. （4） Lacking of exploring of the towns＇identity, which is extracted from towns, is the main cause of the losing of the towns＇ character.
