内蒙古发展生态农业的宏观调控对策研究

发展生态农业是内蒙古农业可持续发展的必然要求，根据所处的地理位置和气候条件，内蒙古比较适宜发展高效节水农业、沙产业和观光农业。宏观调控对策对实现发展生态农业的战略目标具有决定性意义。     

黄河大柳树枢纽供水区生态绿洲建设研究

规划中的黄河大柳树枢纽供水区，即宁、蒙、陕、甘干旱风沙区，土地荒漠化严重．通过建设800O～13300km^2生态绿洲并将其作为生态移民基地，将减轻非绿洲区人口超载压力，为实施旱耕地退耕还草还林工程和天然草场封育工程创造条件，促进该区的可持续发展．     

滹沱河湿地植物群落的种间关系研究

在样方调查的基础上，采用x^2检验和Pearson相关系数，研究了滹沱河湿地植物群落的种间关联性，对种间相关的测定结果进行了生态分析，结果表明：滹沱河湿地植物群落的42种给管植物可分为四个生态组群，即中旱生植物生态组群、中生植物生态组群、湿生植物生态组群和水生植物生态组群，讨论了x^2检验法和Pearson相关系数法的生态学意义，此外，还分析了种间关联、种间相关与环境因子的关系。     

论生态存在与生态意识

生态存在是生态哲学的一个基本范畴，它有自己独特的涵义、特点和构成要素，生态存在和生态意识的关系问题是生态哲学的基本问题。学术界存在着脱离生态存在而单纯研究生态意识的倾向，必须加以批判。不是人们的生态意识决定人们的生态存在，相反地．是人们的生态存在决定人们的生态意识，生态意识是生态存在的反映。     

Rapid cold hardening process of insects and its ecologically adaptive significance

In contrast to overwintering cold hardening, a rapid cold hardening process has recently been described in insects. This process can rapidly enhance cold tolerance of insects in several hours or even minutes. The characteristics of rapid cold hardening include inducing conditions, cold hardening effects, and fitness costs. Physiological and biochemical mechanisms of rapid cold hardening include rapid changes in the phospholipid composition and the increase in hemolymph osmolalities, polyols production, proline and cold-induced proteins. Moreover, there are different views about the ecologically adaptive significance of rapid cold hardening in insects. This paper reviews research results about rapid cold hardening of insects since 1987, focusing on forms of cold injury, strategies of cold tolerance, and definitions, characteristics, physiological and biochemical mechanisms and adaptive significance of rapid cold hardening.

A Study on Forest Species Diversity and Its Ecological Service Function in the Plateau Area of Western Sichuan

This paper presents a study on species diversity and its ecological service function in the plateau area in western Sichuan. The results show that species diversity in the plantations on the cutover land has a tendency to increase and that its ecological service function is to be improved with stand age growing. The species diversity in forest communities is also gradually increased on different succession stage till reaching a climax level. But the species diversity in the climax community is slightly decreased before it reaches a relatively constant status. Ecological service function of diversity is gradually strengthened with the progress of succession. In addition, species diversity in a stand in a similar site and at a same age differs among forest types. Species diversity index within a coniferous and broad-leaved mixed forest is larger than that within a coniferous forest. Meanwhile, species diversity enriches as the tree density increases.
