ABSTRACT The serious deterioration of the ecological environment comes from a large
number of geological disasters. These disasters were caused
by a number of engineering activities. Ecological restoration
is an important measure to reduce geological disasters and protect
the ecological environment. On the basis of the introduction
of cast-in-situ grids technology, external-soil spray seeding
technology and vegetation bag technology, according to the ecological
restoration experiment of the road slope attach to the Three
Gorges Pumped-Storage Power Station in Hohhot, decision analysis
of slope ecological restoration is done with AHP. It is
shown that in arid and semi-arid area, selection of slope ecological
restoration scheme mainly needs considering the ecological effect
and stability. The major factor of ecological effects is survival
rate of vegetation. The major factor of stability is the stability
in a whole. Cast-in-situ grids technology will be the first
choice for ecological restoration of road slope in arid and
semi-arid area. This study provides reference for decision of
the slope ecological restoration in arid and semi-arid region. Keywords: AHP; decision analysis; ecological restoration; slope ABSTRAK Kemerosotan serius berkaitan persekitaran ekologi berlaku disebabkan banyak
bencana geologi. Bencana ini telah disebabkan oleh beberapa
aktiviti kejuruteraan. Pemulihan ekologi merupakan langkah penting
untuk mengurangkan bencana geologi dan melindungi persekitaran
ekologi. Berdasarkan pengenalan teknologi grid tuangan-in-situ, teknologi penyemburan pembenihan tanah luar dan teknologi
tumbuhan beg, menurut pengalaman pemulihan ekologi cerun jalan
bersambung dengan Stesen Simpanan Pam Three Gorges di Hohhot,
keputusan analisis pemulihan ekologi cerun dilakukan dengan
AHP. Keputusan menunjukkan bahawa di kawasan gersang dan
separa gersang, pemilihan skim pemulihan ekologi cerun perlu
mempertimbangkan kesan ekologi dan kestabilan. Faktor utama
kesan ekologi ialah kadar kemandirian tumbuh-tumbuhan. Faktor
utama kestabilan ialah kestabilan secara menyeluruh. Teknologi
grid tuangan-in-situ akan menjadi pilihan pertama untuk pemulihan
ekologi cerun jalan di kawasan gersang dan separa gersang. Kajian
ini memberi rujukan untuk membuat keputusan tentang pemulihan
ekologi cerun di kawasan gersang dan separa-gersang. Kata
