In natural vegetation area, where mainly are forest land, the yearly relative humidity and precipitation of spring are the driving forces to the change of NDVI. In brush and shrub area, the change of NDVI is driven by the precipitation and relative humidity of autumn. In grassland and rare tree bush grassland district, the main driving forces are human factors, and the driving mechanism is that farmland and cropping sown area are negative to the change of NDVI, but society factors are positive.

对于以林地为主的自然植被区植被覆盖变化，主要受到春季降水、春季湿度和年均湿度的正驱动，黄淮海地区的北部主要为干旱、半干旱区，因此春季降水偏多会利于植被生长；灌丛和萌生矮林区，秋季降水和秋季湿度对其植被NDVI变化呈负驱动；草原和稀树灌木草原区植被覆盖的变化，耕地面积、作物播种面积对之为负驱动，而其他社会经济因子则为正驱动。

The products can substitute solid clay bricks, avoid damage to the earth, curb the emission of CO2, and protect the environment and farmland. Other special characteristics include being light weight (about 1/3 of a double side plastering wall), having a thickness of 9 to 12 cm, having fire resistance and thermal insulation (A-level non-combustible insulation material), being convenient for construction (plate-type assembling and dry construction), and being cost effective (An enclosure wall of this material can reduce construction costs by 15% to 20%). It has advantages over solid clay bricks in terms of weight, energy-saving capacity, recycling and environmental protection.

产品不仅可以替代实心粘土砖，扭转烧砖毁地局面，遏制CO2的排放，保护环境和耕地，而且具有自重轻（约为双面抹灰墙的1/3）、墙体薄（厚9~12M）、防火与保温、施工便捷（采用板块式拼装、干式作业）、投资省（利用其作为建筑围护内外墙，可节省建筑投资10%~15%）等特点，在&轻质、节能、利废、环保&等方面均优于实心粘土砖。

In recent years, Jilin Province takes as the national important industry and agriculture production base, its economy has obtained the huge development because of increasing the development dynamics, and it has consumed the massive land resource, but along with this, a series questions such as cultivated area reduction, land environmental pollution and soil erosion appeared. The positive cycle of ecosystem has already been destructed.

This thesis was guided by the Sustained Development Theory, exampled by the carrying out of the engineering of Anhui Province, analyzing the opportunity and challenge which it brought to us, and further, on the viewpoint of economics, researching the contradiction existing between the engineering and the economical development of local area, bring out an idea that how to improve the local economics by the turning point of the returning farmland engineering.

The results show: 1 In the rapid urbanization, the human activities in Beijing area are becoming stronger and stronger with the accelerating trend; 2 The rapid expansion of the urban land by encroaching the cultivated land in the plain area and the land use adjustment within the no-urban area are the main characteristics of the land use/cover change in Beijing; 3 The land use/cover from the center city, the fringe area to the exurb area show the obvious character of the spatial-temporal grads change with the most strong changes taking place in the fringe area.

发现：1伴随着快速的城市化进程，北京地区人类活动对区域整体的改造和影响正在深入，并且表现出加速趋势；2城镇用地通过占用耕地在平原区的快速扩展和非城镇用地内部的结构调整是北京地区土地利用/覆盖变化的基本特征。3从北京城市核心区经城乡过渡区到郊区，土地利用/覆盖变化表现出明显空间分布和时间变化上的梯度性，其中城乡过渡区是北京地区土地利用/覆盖变化最明显、也是最剧烈的区域(第4章)。
