岩溶山地土地整理模式研究

西南岩溶山地是典型的脆弱生态环境,与经济发达地区相比,有其自身的土地资源特点、生态特点和社会特点。文章以此为基础,提出岩溶山地土地整理的原则、思路,认为岩溶山地的土地整理应从高标准基本农田建设、阶梯式还林退耕和辐射式生态重建、实行土地双轨制、直接对农户投资着手等,提出不同空间尺度如县市、乡镇、村组、农户土地整理的具体模式。非耕地资源开发是岩溶山地土地整理的重点。

Urbanization: the challenge for the next century

This article summarizes a new 1996-97 report from the World Resources Institute, the UN Environmental Program, the UN Development Program, and the World Bank, which describes a future with increased levels of urbanization that were reshaping the physical and social environment. Urbanization increased economic growth and environmental degradation. By the year 2000, 50% of the world population will live in urban areas. Cities are the center of economic activity. Consumption is the highest in cities. Cities produce the most pollution and waste. Three issues are particularly crucial to survival: the water supply, sanitation, and water resource management. Neglect of these and other environmental issues is likely to have important consequences in both developing and developed countries. The greatest growth in urban areas is occurring in developing countries. Cities in developing countries have huge populations living in poverty. The poor in either rural or urban areas are confronted with lack of access to clean water, to sanitation, and to housing. There is overcrowding and exposure to industrial wastes and air pollution. There is a need for policy reform, stronger institutions, and enlightened political leadership. Cities need to improve their environment and to strengthen local government and implement poverty reduction programs. Reform of urban policies must be accompanied by effective urban governance. Community-based approaches are essential. Broad-based support is needed for changes in strategies and practices and for attainment of a more sustainable environment.
