  1. Then i discussed methane desorption properties including cbm - bearing saturation, critical desorption pressure, the ratio between critical desorption pressure and original coal reservoirs pressure and difference of terra decompression ; cbm - bearing characteristics of coal seams including measured / academic cbm - bearing content, coalbed methane resources content and cbm resources abundance, etc. the author respectively gave a brief account of the basic characteristics of ancient and today ' s geothermic field at 1000m and 2000m depth, coal measure strata pressure field at the depth less than 1600m, structural stress field from jurassic to present, and ancient and today ' s fluid potential field ( that is water potential and gas potential distributing in coal measure strata )

    分別簡述了準噶爾盆地1000m及2000m深度今古地溫場、 1600m以淺的煤系地層壓力場、侏羅紀至今地應力場及煤系地層水勢與氣勢分佈的今古流體勢場基本特徵，進而對這「四場」特徵及其互動關系與煤儲層物性、可采性及煤層氣聚集的關系進行了探討。從構造背景、構造演化及構造類型幾方面論述了本區構造作用的控氣特徵。
  2. The main results are as follows based on field survey and analysis : 1 soil water is the water stored in the soil that can be absorbed by plants in some depth of soil, and the efficiency of soil water plays the critical role in plant growth and development. so soil water is the resource that is very crucial to vegetation

    經過兩年多的野外實地考察和室內分析，取得了如下主要研究結果： 1土壤水分是指貯存在土壤中一定深度范圍內能被植物吸收利用的土壤水含量，土壤水分的有效性對植物的生長發育起著最為關鍵的作用，因此，土壤水分應屬於水資源的范疇，是水資源的重要組成部分。
