摘要
我国沿海地区是个多灾地区,主要自然灾害有台风、干旱、水土流失等,且缺少木材和烧柴。作者分析了我国沿海防护林的现状,进而提出建设生态经济型沿海防护林的构想,即不仅发挥其生态防护功能,还应充分发挥其社会经济功能。沿海防护林体系应作为生态经济产业来进行开发和建设。而因地制宜,科学合理地确定沿海防护林体系的组成,优化其结构,则是实现稳定高效多功能的关键。
Coastal areas in China are calamity-frequented areas. The chief naturaldisasters are typhoon (gale, rain storm, tide, sea billows, spouts), drought,fall cold wind, frost, water loss and soil erosion. Here timber and faggots are inshort supply. After giving a general picture of the protection forests in coastalareas, conceptions concerning establishment of ecologic economic protection forestsin these areas are given. The new protection forests should have not only ecologicprotective function and benefits, but also full social economic function andbenefits. That is, they should have a double role to play. There should be a ration-al program of land utilization for optimum allotment to agriculture, forestry, ani-mal husbandry, fishery, commerce and side line production, and for full play ofthe potential productivity of various resources such as sunshine, heat, water, air, soil, living organism, human intelligence and labor. Let there be a biotic complexconsisting of various tree species, various forest types, various plants with multipleuse and various species of living organisms, which possess multiple useful functionsand give diverse economic returns. Thus an ecologic system with improvedfunctions, biotic stability and higher, ecologic economic returns can be formed, soas to keep a virtuous circulation of materials and energy. The development and con-struction of protection forest system in coastal areas should be treated as an ecologiceconomic industry. The composition of the system and its optimum structure inaccordance with local conditions and scientific principles is the key to having multi-ple functions with high effect and stability.
