Since it , qinghai spruce shows fragmentized . the statistics for the primary landscape elements distributed in different height state farmland concentrate between 2550 to 3000 meters in altitude ; grassland distribute 3000 - 4350m in altitude ; qinghai spruce distribute 2550 - 3000m in altitude . qinghai spruce concentrate in northern slope , northeast slope , east slope and northwest slope 对主要景观组分在不同海拔高度分布的统计表明，农田主要集中分布在海拔2100 - 3000m之间；牧草地主要集中分布在海拔3000 - 4350m之间，其面积占到牧草地总面积的86 . 7 ；青海云杉林主要集中分布在海拔2550 - 3000m的山地中下部，约占青海云杉林总面积的80 . 9 。
The paper deals with the main problems of the land resource in sichuan province : both the predominant land form types and the high quality land types make up little share ; not only the photo - temperature productivity but also the land potential productivity need raising ; the quantity of cultivated land , forest land and grazing land averaged to great population is lacking , which indicates that the contradiction between man and land is outstanding ; on the one hand the reserved land resource suitable for cultivation is insufficient , on the other hand the land difficult to cultivate accounts for great share ; the level of land exploitation and utilization is low and the land productivity develops slowly 四川土地资源的主要问题是优势地貌类型占有量少；优质地类比重不大、光温潜力和土地生产潜力的发挥不够；人多地少，人均耕地、林地和牧草地不足，各地类人均占有量极低，人地矛盾十分突出；宜农耕地后备资源贫乏，难利用土地比重大；土地开发利用程度低，土地生产力水平发挥不够。
In terms of the change magnitude of land use of main urban areas : land for residential areas and mining cultivated land grassland forest land idle land land for traffic other agricultural land land for water facilities garden land ; in terms of change magnitude of land use of various counties ( cities ) under its administration : grassland idle land cultivated land forest land land for water facilities other agricultural land land for residential areas and mining garden land land for traffic 主城区土地利用变化强度是居民点及工矿用地耕地牧草地林地未利用地交通用地其他农用地水利设施用地园地；而下辖各县（市）土地利用变化强度是牧草地未利用地耕地林地水利设施用地其他农用地居民点及工矿用地园地交通用地。
Ecological features , function indicators and social - human impact together constitute the fundermental system of regional ecosystem health assessment . haxi forestry center is located in tianzhu of gansu province . in view of the natural conditions , land use type and forest map , we classify the research area into 15 landscape types 甘肃天祝县哈溪林区位于祁连山东段，依据哈溪林区的自然条件、土地类型和林相图，将研究区划分为苗圃，未成林地，宜林地，农田，牧草地，荒地，青海云杉林，祁连圆柏，针叶混交林，杨类阔叶林，红桦、榆、山杨硬阔林，针阔混交林、灌木林、疏林地和阔叶混交林等15种景观类型。
The escarpment has been the location for colonization and towns throughout texas history because of the natural resources associated with the fault - plenty of natural building stone ourcrops on the escarpment , water pors from springs , timber can be gotten on teh wooded hills , and the adjacent fertile prairies support a strong agricultural economy 它创立了balcones峭壁。在历史上它曾是开拓者之源。就地的自然建筑石，来自于泉水的自然水源，山丘的树木木材和临接的肥沃的牧草地，形成了强硬的奥斯汀农业经济。
The land occupied in the process of urbanization is divided into cropland , garden plot , woodland , grass / rangeland , water area , wilderness . according to the characteristic of land occupation in the process of urbanization , the ecological loss of land is environmental loss , land restoration costs and available ecological loss 本文将城镇化进程中占用的土地类型分为耕地、园地、林地、牧草地、水域、未利用地六种，根据城镇化进程中占用土地造成土地生态损失的特点，将土地生态系统的生态损失分为有效生态损失、环境损失、恢复费用三部分。
Land use situation analysis using gis technology and landscape ecology theory , the research shows that : 1 ) the contradiction between the people and the land is sharp day by day ; 2 ) the land quality reduces , and the water and soil suffers from pollution , so the ecological environment worse progressively ; 3 ) the utilization of water resources is insufficient ; 4 ) the scientific and technological content of agricultural production is low , and the agricultural modernization level is not so high ; the proportions of forest land , field and herb is small 宝应县土地利用现状分析采用gis技术和景观生态学理论方法开展研究，结果表明该区域的土地利用存在以下问题：人地矛盾日趋尖锐：土地质量下降，水土遭到污染，生态环境逐步恶化；水面和水资源利用不充分；农业生产的科技含量低，农业现代化水平不高：林地、园地和牧草地比重太小。
