一、基本情况辽宁省位于东北地区的南部,地处中纬度,属温带大陆性季风气候区。全省土地总面积为14,573,933公顷,占全国总土地面积的1.5%,居全国30个省(市、自治区)第21位。全省地势由北向南自东西两侧向中部倾斜,东西两侧为山地丘陵,约占全省总土地面积62%,中部为东北向西南缓倾的长方形平原,约占30%,水域及其他面积约占8%。故称“六山、一水、三分田”。二、发展速生丰产用材林的可能性根据辽宁省自然地理所处位置和气候、土壤,可适宜发展速生林的土地资源以及劳动力等多方面情况分析,大力发展速生丰产林是完全可能的。特别是近两年来实行了国家、集体和个人造林一齐上蓬勃发展的好形势。由于造林政策的落实,广大群众对植树造林的积极性持续高涨,勇于在“两山”上投资投劳,造林承包大户逐年增多。据统计1985年全省农村已有造林专业户2万多个,群众个人投资造林250多万元,个人造林面积达15.8万公顷,占全省造林总面积的49%。今后随着农村经济体制的深入改革,林业经济联合体和专业户必将有更大的发展,一定会促进造林事业的飞跃。1.已营造速生丰产林的情况 First, the basic situation Liaoning Province is located in the southern part of the northeast region, is located in the mid-latitude, is a temperate continental monsoon climate zone. The total land area of ​​the province is 14,573,933 hectares, accounting for 1.5% of the total land area in the country, ranking 21st in 30 provinces (municipalities and autonomous regions) across the country. The province’s terrain from north to south from the east and west sides tilt to the central, east and west sides of the mountain hills, accounting for about 62% of the total land area of ​​the province, the central northeast gentle southwest gentle rectangular plain, about 30%, waters and other Area accounts for about 8%. Therefore, “Six Mountains, a water, three points Tian.” II. Possibility of Developing Fast-growing and High-yielding Timber Forest According to the analysis of many factors such as the location and climate of the natural geography of Liaoning Province, soil, land resources suitable for the development of fast-growing forests, and labor force, it is quite possible to vigorously develop fast-growing and high-yield forests. In particular, the past two years have brought about a good situation in which the state, collective and individual afforestation are booming together. Due to the implementation of the afforestation policy, the masses of the people have been steadily increasing their enthusiasm for afforestation and afforestation, and have dared to invest in the “two mountains” and large afforestation contractors have been increasing year by year. According to statistics, more than 20,000 specialized afforestation households have been established in the rural areas in 1985 in the province. More than 2.5 million yuan have been invested in afforestation by individuals and 158,000 hectares have been afforestation sites, accounting for 49% of the total afforestation area in the province. In the future, with the in-depth reform of the rural economic system, there will surely be more developments in the forestry economy consortia and specialized households and a great leap forward in afforestation will surely be promoted. 1.
