    There were some harmful phenomena on agriculture in this country now，for example，unsuited structure，lower profit，little support on policy，poor market competitiveness of products，etc. It was suggested that the ratio relationship between agriculture，forestry，animal husbandry，fishery should be adjusted，and that some structure，for example，agricultural industries，products，essential factors of production and trade should be adjusted too. All of this is based on a whole production system and sustainable development of rural economy. Agriculture should be evaluated from various angles and different stratifications。It was also suggested that superior industry，especially for characteristic products，should be developed energetically，yield of croup should be controlled to suitable scope according to plan，and the ratio of animal husbandry of whole agriculture should be increased。It is more important that the role of technology and improvement of production regulations should not be neglected，a simple change of breeds within cropping could not free whole agriculture from backwardness at all.

    Vegetation and soil is the two most active factors of landscape and the important content of evaluation for cropland to forest. The relationship between them is central to ecological research. In the loess hilly region, study of relationship is required for understanding of landscape ecological processes and restoration of cropland to forest. Spatio-temporal variance and correlation of (vegetation) species richness, diversity, evenness, soil organic matter, total nitrogen, total phosphorus of cropland to forest and their interaction at different spatial scales and habitats in the loess hilly region are analyzed in this paper. The vegetation index of cropland to forest in area scale is less than that in catchment scale, but it has more variance. To come near significant and significant positive correlations between species richness and evenness, species diversity and evenness, soil organic matter and total nitrogen were revealed at two scales and habitats studied. Different spatio-temporal patterns of vegetation characteristics and soil properties of cropland to forest were found, but no significant correlations between were observed in two scales. These results indicated vegetation characteristics and soil properties of cropland to forest were controlled by others environmental factors or interferential process. These factors or interferential process resulted in spatio-temporal variance vegetation characteristics and soil properties of cropland to forest.
